Class HiveHBaseTableInputFormat

java.lang.Object
  org.apache.hadoop.mapreduce.InputFormat<org.apache.hadoop.hbase.io.ImmutableBytesWritable,org.apache.hadoop.hbase.client.Result>
      org.apache.hadoop.hbase.mapreduce.TableInputFormatBase
          org.apache.hadoop.hive.hbase.HiveHBaseTableInputFormat

All Implemented Interfaces:

org.apache.hadoop.mapred.InputFormat<org.apache.hadoop.hbase.io.ImmutableBytesWritable,ResultWritable>

public class HiveHBaseTableInputFormat
extends org.apache.hadoop.hbase.mapreduce.TableInputFormatBase
implements org.apache.hadoop.mapred.InputFormat<org.apache.hadoop.hbase.io.ImmutableBytesWritable,ResultWritable>

HiveHBaseTableInputFormat implements InputFormat for HBase storage handler tables, decorating an underlying HBase TableInputFormat with extra Hive logic such as column pruning and filter pushdown.
