SerDe & ObjectInspector for RowContainer mismatch with the input data
---------------------------------------------------------------------
Key: HIVE-1037
URL: https://issues.apache.org/jira/browse/HIVE-1037
Project: Hadoop Hive
Issue Type: Bug
Reporter: Ning Zhang
Assignee: Ning Zhang
In CommonJoinOperator, RowContainer is created for each input table with the
SerDe and ObjectInspector to serialize/deserialize that row to persistent
storage. The serde/OI could be null in the case of the value columns are pruned
by column pruner. An example query is
select count(1) from A join B on A.key=B.key;
Another case of mismatch is that the tableDesc was initialized at compile time
before the column pruner take place. This could cause inconsistency in the
SerDe/OI with the input data. This should be moved to execution time when the
join operator is initialized.
