Subject [jira] [Created] (HIVE-12202) NPE thrown when reading legacy ACID delta files
Date Fri, 16 Oct 2015 10:59:05 GMT
Elliot West created HIVE-12202:

             Summary: NPE thrown when reading legacy ACID delta files
                 Key: HIVE-12202
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 1.3.0
            Reporter: Elliot West
            Assignee: Elliot West

When reading legacy ACID deltas of the form {{delta_$startTxnId_$endTxnId}} a {{NullPointerException}}
is thrown on:

if(dmd.getStmtIds().isEmpty()) {

The older ACID data format (pre-Hive 1.3.0) which does not include the statement ID, and code
written for that format should still be supported. Therefore the above condition should also
include a null check or alternatively {{AcidInputFormat.DeltaMetaData}} should never return
null, and return an empty list in this specific scenario.
