URL: https://github.com/apache/hive/pull/1092


   Immutable dumps can be loaded into multiple clusters. Currently, after every load it creates
an acknowledgement file. This prevents reuse of the repl dump. We can use hive.repl.dump.skip.immutable.data.copy
and skip the load ack file. This would enable users to reuse immutable repl dumps.

> "{{hive.repl.dump.metadata.only=true"}} is not currently honored during "{{repl load"}}.
Currently, it ends up copying all files even if this option is specified in "repl load". 
E.g
> {noformat}
> repl load airline_ontime_orc into another_airline_ontime_orc with ('hive.repl.rootdir'='s3a://blah/',
'hive.repl.dump.metadata.only'='true'); {noformat}
> Alternatively, we can use {{hive.repl.dump.skip.immutable.data.copy}} and skip the load
ack file. This would enable users to reuse immutable repl dumps.
