Package org.apache.hadoop.hive.llap

Class Summary

Class	Description
ChannelOutputStream	OutputStream to write to the Netty Channel
DebugUtils	A class that contains debug methods; also allows enabling the logging of various trace messages with low runtime cost, in order to investigate reproducible bugs.
LlapArrowRecordWriter<K extends org.apache.hadoop.io.Writable,V extends org.apache.hadoop.io.Writable>	Writes Arrow batches to an ArrowStreamWriter.
LlapCacheAwareFs	This is currently only used by Parquet; however, a generally applicable approach is used - you pass in a set of offset pairs for a file, and the file is cached with these boundaries.
LlapHiveUtils	Covers utility functions that are used by LLAP code and depend on Hive constructs e.g.
LlapOutputFormat<K extends org.apache.hadoop.io.Writable,V extends org.apache.hadoop.io.Writable>
LlapOutputFormatService	Responsible for sending back result set data to the connections made by external clients via the LLAP input format.
LlapRecordWriter<K extends org.apache.hadoop.io.Writable,V extends org.apache.hadoop.io.WritableComparable>
ProactiveEviction	Through this class the caller (typically HS2) can request eviction of buffers from LLAP cache by specifying a DB, table or partition name/(value).
ProactiveEviction.EvictionRequestTask	The executable task to carry out request sending.
ProactiveEviction.Request	Holds information on entities: DB name(s), table name(s), partitions.
ProactiveEviction.Request.Builder	Lets callers specify what entities are requested to be evicted, and builds a Request instance accordingly.
SchemaAwareCacheKey	Cache key that stores schema hash.
WritableByteChannelAdapter	Provides an adapter between WritableByteChannel and ChannelHandlerContext.
