Class IntegrationTestBulkLoad.LinkedListCheckingMapper

java.lang.Object

org.apache.hadoop.mapreduce.Mapper<org.apache.hadoop.hbase.io.ImmutableBytesWritable,org.apache.hadoop.hbase.client.Result,KEYOUT,VALUEOUT>

org.apache.hadoop.hbase.mapreduce.TableMapper<IntegrationTestBulkLoad.LinkKey,IntegrationTestBulkLoad.LinkChain>

org.apache.hadoop.hbase.mapreduce.IntegrationTestBulkLoad.LinkedListCheckingMapper

Enclosing class:

IntegrationTestBulkLoad

public static class IntegrationTestBulkLoad.LinkedListCheckingMapper
extends org.apache.hadoop.hbase.mapreduce.TableMapper<IntegrationTestBulkLoad.LinkKey,IntegrationTestBulkLoad.LinkChain>

Mapper to pass over the table. For every row there could be multiple chains that landed on this row. So emit a linkKey and value for each.
