Review comment:
You can add this test in the mini hdfs set up to make sure data copy is
happening correctly in case of lazy load false and true.

> Currently the iterator used while copying table data is memory based. In case
> of a database with very large number of table/partitions, such iterator may
> cause HS2 process to go OOM.
> Also introduces a config option to run data copy tasks during repl load
> operation.
