> 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.
