Will Temperley commented on HBASE-7024: --------------------------------------- This is marked as fixed, but the unnecessary restrictions on the types of outputKeyClass and outputValueClass are still in place. > TableMapReduceUtil.initTableMapperJob unnecessarily limits the types of > outputKeyClass and outputValueClass > ----------------------------------------------------------------------------------------------------------- > > Key: HBASE-7024 > URL: https://issues.apache.org/jira/browse/HBASE-7024 > Project: HBase > Issue Type: Improvement > Components: mapreduce > Reporter: Dave Beech > Priority: Minor > Fix For: 0.95.0 > > Attachments: HBASE-7024.patch > > > The various initTableMapperJob methods in TableMapReduceUtil take > outputKeyClass and outputValueClass parameters which need to extend > WritableComparable and Writable respectively. > Because of this, it is not convenient to use an alternative serialization > like Avro. (I wanted to set these parameters to AvroKey and AvroValue). > The methods in the MapReduce API to set map output key and value types do not > impose this restriction, so is there a reason to do it here? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
