> 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.
