> Key: HIVE-24918
> URL: https://issues.apache.org/jira/browse/HIVE-24918
> Project: Hive
> Issue Type: New Feature
> Reporter: Haymant Mangla
> Assignee: Haymant Mangla
> Priority: Major
> Labels: pull-request-available
> Time Spent: 6h 20m
> Remaining Estimate: 0h
>
> To handle:
> a) Whenever user wants to go ahead with failover, during the next or
> subsequent repl dump operation upon confirming that there are no pending open
> transaction events, It should create a _failover_ready marker file in the
> dump dir. This marker file would contain scheduled query name
> that has generated this dump.
> b) Skip next repl dump instances once we have the marker file placed.
