  6. val UPDATE_INPUT_METRICS_INTERVAL_RECORDS: Int

    Number of records to update input metrics when reading from HadoopRDDs.

    Number of records to update input metrics when reading from HadoopRDDs.

    Each update is potentially expensive because we need to use reflection to access the Hadoop FileSystem API of interest (only available in 2.5), so we should do this sparingly.

    Create a file on the given file system, optionally making sure erasure coding is disabled.

    Create a file on the given file system, optionally making sure erasure coding is disabled.

    Disabling EC can be helpful as HDFS EC doesn't support hflush(), hsync(), or append(). https://hadoop.apache.org/docs/r3.0.0/hadoop-project-dist/hadoop-hdfs/HDFSErasureCoding.html#Limitations

  35. def propertySources(hadoopConf: Configuration, key: String): String

    Extract the sources of a configuration key, or a default value if the key is not found or it has no known sources.

    Extract the sources of a configuration key, or a default value if the key is not found or it has no known sources. Note that options provided by credential providers (JCEKS stores etc) are not resolved, so values retrieved by Configuration.getPassword() may not be recorded as having an origin.

    hadoopConf

    hadoop configuration to examine.

    key

    key to look up

    returns

    the origin of the current entry in the configuration, or the empty string.
