------------------------------------------
Summary: 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
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.
