------------------------------------------
Summary: Common Merge join throwing class cast exception
Key: HIVE-22197
URL: https://issues.apache.org/jira/browse/HIVE-22197
Project: Hive
Issue Type: Bug
Components: Hive
Affects Versions: 4.0.0
Reporter: mahesh kumar behera
Assignee: mahesh kumar behera
Fix For: 4.0.0
In DummyStoreOperator the row is cached to fix HIVE-5973. The row is copyed and
stored in the writable format, but the object inspector is initialized to
default. So when join operator is fetching the data from dummy store operator,
its getting the OI is Long and the row as LongWritable. This is causing the
class cast exception.
