>          Components: Spark
>    Affects Versions: 1.2.1, 2.0.0
>            Reporter: Szehon Ho
>            Assignee: Chinna Rao Lalam

> Currently Hive on Spark Mapjoin replicates small table file to a hard-coded value of
10.  See SparkHashTableSinkOperator.MIN_REPLICATION. 
> When dfs.replication.max is less than 10, HoS query fails.  This constant should cap
at dfs.replication.max.
> Normally dfs.replication.max seems set at 512.
