[jira] [Created] (DRILL-7341) Vector reAllocation may fails after exchange.

Oleg Zinoviev created DRILL-7341:
------------------------------------

             Summary: Vector reAllocation may fails after exchange.
                 Key: DRILL-7341
                 URL: https://issues.apache.org/jira/browse/DRILL-7341
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.16.0
            Reporter: Oleg Zinoviev
         Attachments: stacktrace.log

There are several methods that modify the BaseDataValueVector#data field. 
Some of them, such as BaseDataValueVector#exchange, do not change allocationSizeInBytes. 
Therefore, if BaseDataValueVector#exchange was executed for vectors with different size, *ValueVector#reAlloc may create a buffer of insufficient size.
