Vihang Karajgaonkar reassigned HIVE-21932:
------------------------------------------
> IndexOutOfRangeExeption in FileChksumIterator
> ---------------------------------------------
>
> Key: HIVE-21932
> URL: https://issues.apache.org/jira/browse/HIVE-21932
> Project: Hive
> Issue Type: Bug
> Reporter: Vihang Karajgaonkar
> Assignee: Vihang Karajgaonkar
> Priority: Major
>
> According to definition of {{InsertEventRequestData}} in
> {{hive_metastore.thrift}} the {{filesAddedChecksum}} is a optional field. But
> the FileChksumIterator does not handle it correctly when a client fires a
> insert event which does not have file checksums. The issue is that
> {{InsertEvent}} class initializes fileChecksums list to a empty arrayList to
> the following check will never come into play
> {noformat}
> result = ReplChangeManager.encodeFileUri(files.get(i), chksums != null ?
> chksums.get(i) : null,
> subDirs != null ? subDirs.get(i) : null);
> {noformat}
> The chksums check above should include a {{!chksums.isEmpty()}} check as well
> in the above line.
