Hive Metastore Client. The public implementation of IMetaStoreClient. Methods not inherited from IMetaStoreClient are not public and can change. Hence this is marked as unstable. For users who require retry mechanism when the connection between metastore and client is broken, RetryingMetaStoreClient class should be used.

    Drop partitions based on an expression.

    dropPartitions in interface IMetaStoreClient
    
    Parameters:
    
    dbName - database name.
    
    tblName - table name.
    
    partExprs - I don't understand this fully, so can't completely explain it. The second half of the object pair is an expression used to determine which partitions to drop. The first half has something to do with archive level, but I don't understand what. I'm also not sure what happens if you pass multiple expressions.
    
    deleteData - whether to delete the data as well as the metadata.
    
    ifExists - if true, it is not an error if no partitions match the expression(s).
    
    Returns:
    
    list of deleted partitions.
    
    Throws:
    
    NoSuchObjectException - No partition matches the expression(s), and ifExists was false.

    Get a list of table names that match a filter. The filter operators are LIKE, <, <=, >, >=, =, <> In the filter statement, values interpreted as strings must be enclosed in quotes, while values interpreted as integers should not be. Strings and integers are the only supported value types. The currently supported key names in the filter are: Constants.HIVE_FILTER_FIELD_OWNER, which filters on the tables' owner's name and supports all filter operators Constants.HIVE_FILTER_FIELD_LAST_ACCESS, which filters on the last access times and supports all filter operators except LIKE Constants.HIVE_FILTER_FIELD_PARAMS, which filters on the tables' parameter keys and values and only supports the filter operators = and <>. Append the parameter key name to HIVE_FILTER_FIELD_PARAMS in the filter statement. For example, to filter on parameter keys called "retention", the key name in the filter statement should be Constants.HIVE_FILTER_FIELD_PARAMS + "retention" Also, = and <> only work for keys that exist in the tables. E.g., filtering on tables where key1 <> value will only return tables that have a value for the parameter key1. Some example filter statements include: filter = Constants.HIVE_FILTER_FIELD_OWNER + " like \".*test.*\" and " + Constants.HIVE_FILTER_FIELD_LAST_ACCESS + " = 0"; filter = Constants.HIVE_FILTER_FIELD_OWNER + " = \"test_user\" and (" + Constants.HIVE_FILTER_FIELD_PARAMS + "retention = \"30\" or " + Constants.HIVE_FILTER_FIELD_PARAMS + "retention = \"90\")"

```
    Description copied from interface: IMetaStoreClient
    
    Initiate a batch of transactions. It is not guaranteed that the requested number of transactions will be instantiated. The system has a maximum number instantiated per request, controlled by hive.txn.max .batch.open in hive-site.xml. If the user requests more than this value, only the configured max will be returned.
    Increasing the number of transactions requested in the batch will allow applications that stream data into Hive to place more commits in a single file, thus reducing load on the namenode and making reads of the data more efficient. However, opening more transactions in a batch will also result in readers needing to keep a larger list of open transactions to ignore, potentially slowing their reads. Users will need to test in their system to understand the optimal number of transactions to request in a batch.
    
    Specified by:
    
    openTxns in interface IMetaStoreClient
    
    Parameters:
    
    user - User who is opening this transaction. This is the Hive user, not necessarily the OS user. It is assumed that this user has already been authenticated and authorized at this point.
    
    numTxns - number of requested transactions to open
    
    Returns:
    
    list of opened txn ids. As noted above, this may be less than requested, so the user should check how many were returned rather than optimistically assuming that the result matches the request.

    Description copied from interface: IMetaStoreClient
    
    Like commitTxn but it will atomically store as well a key and a value. This can be useful for example to know if the transaction corresponding to txnid has been committed by later querying with DESCRIBE EXTENDED TABLE. TABLE_PARAMS from the metastore must already have a row with the TBL_ID corresponding to the table in the parameters and PARAM_KEY the same as key in the parameters. The way to update this table is with an ALTER command to overwrite/create the table properties.
    
    Specified by:
    
    commitTxnWithKeyValue in interface IMetaStoreClient
    
    Parameters:
    
    txnid - id of transaction to be committed.
    
    tableId - id of the table to associate the key/value with
    
    key - key to be committed. It must start with "_meta". The reason for this is to prevent important keys being updated, like owner.
    
    value - value to be committed.
    
    Throws:
    
    NoSuchTxnException - if the requested transaction does not exist. This can result fro the transaction having timed out and been deleted by the compactor.

```
    Description copied from interface: IMetaStoreClient
    
    Request a set of locks. All locks needed for a particular query, DML, or DDL operation should be batched together and requested in one lock call. This avoids deadlocks. It also avoids blocking other users who only require some of the locks required by this user.
    If the operation requires a transaction (INSERT, UPDATE, or DELETE) that transaction id must be provided as part this lock request. All locks associated with a transaction will be released when that transaction is committed or rolled back.
    *
    Once a lock is acquired, IMetaStoreClient.heartbeat(long, long) must be called on a regular basis to avoid the lock being timed out by the system.
    
    Specified by:
    
    lock in interface IMetaStoreClient
    
    Parameters:
    
    request - The lock request. LockRequestBuilder can be used construct this request.
    
    Returns:
    
    a lock response, which will provide two things, the id of the lock (to be used in all further calls regarding this lock) as well as a state of the lock. If the state is ACQUIRED then the user can proceed. If it is WAITING the user should wait and call IMetaStoreClient.checkLock(long) before proceeding. All components of the lock will have the same state.
    
    Throws:
    
    NoSuchTxnException - if the requested transaction does not exist. This can result fro the transaction having timed out and been deleted by the compactor.
    
    TxnAbortedException - if the requested transaction has been aborted. This can result from the transaction timing out.

```
protected String getValidWriteIdList(String dbName,
                                     String tblName)
```
    This method is called to get the ValidWriteIdList in order to send the same in HMS get_* APIs, if the validWriteIdList is not explicitly passed (as a method argument) to the HMS APIs. This method returns the ValidWriteIdList based on the VALID_TABLES_WRITEIDS_KEY key. Since, VALID_TABLES_WRITEIDS_KEY is set during the lock acquisition phase after query compilation ( DriverTxnHandler.acquireLocks -> recordValidWriteIds -> setValidWriteIds ), this only covers a subset of cases, where we invoke get_* APIs after query compilation, if the validWriteIdList is not explicitly passed (as a method argument) to the HMS APIs.

```
    Description copied from interface: IMetaStoreClient
    
    Generic Partition request API, providing different ways of filtering and controlling output. The API entry point is getPartitionsWithSpecs(), which is based on a single request/response object model. The request (GetPartitionsRequest) defines any filtering that should be done for partitions as well as the list of fields that should be returned (this is called ProjectionSpec). Projection is simply a list of dot separated strings which represent the fields which should be returned. Projection may also include whitelist or blacklist of parameters to include in the partition. When both blacklist and whitelist are present, the blacklist supersedes the whitelist in case of conflicts. Partition filter spec is the generalization of various types of partition filtering. Partitions can be filtered by names, by values or by partition expressions.

    Description copied from interface: IMetaStoreClient
    
    Create, update or delete one record in the compaction metrics cache.
    If the metric is not found in the metrics cache, it will be created.

    If the new metric value is below CompactionMetricsDataStruct.getThreshold(), it will be deleted.
