Hi Team, Env: Hive 1.0 on Tez 0.5.3 Query is a simple group-by on top of sequence table.
It fails with below error on tez mode: *java.lang.RuntimeException: org.apache.hadoop.hive.ql.metadata.HiveException: * *java.io.IOException: java.io.IOException: wrong key class: org.apache.hadoop.io.BytesWritable is not class org.apache.hadoop.io.NullWritable * And it works fine in MR mode. Anyone met this issue before? -- Thanks, www.openkb.info (Open KnowledgeBase for Hadoop/Database/OS/Network/Tool)
