> URL: https://issues.apache.org/jira/browse/HIVE-16813
> Project: Hive
> Issue Type: Sub-task
> Components: Hive, repl
> Affects Versions: 2.1.0
> Reporter: Sankar Hariappan
> Assignee: Sankar Hariappan
> Labels: DR, replication
>
> Currently, incremental REPL DUMP use $dumpdir/<eventID> to dump the metadata
> and data files corresponding to the event. The event is dumped in the same
> sequence in which it was generated.
> Now, REPL LOAD, lists the directories inside $dumpdir using listStatus and
> sort it using compareTo algorithm of FileStatus class which doesn't check the
> length before sorting it alphabetically.
> Due to this, the event-100 is processed before event-99 and hence making the
> replica database non-sync with source.
> Need to use a customized compareTo algorithm to sort the FileStatus.
