-----------------------------
Fix Version/s: (was: 1.4.0)
> Partitioned tables should only consider referred partitions in query during
> size estimation for checking against autoBroadcastJoinThreshold
> -------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-7097
> URL: https://issues.apache.org/jira/browse/SPARK-7097
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.1.1, 1.2.0, 1.2.1, 1.2.2, 1.3.0, 1.3.1
> Reporter: Yash Datta
>
> Currently when deciding about whether to create HashJoin or ShuffleHashJoin,
> the size estimation of partitioned tables involved considers the size of
> entire table. This results in many query plans using shuffle hash joins ,
> where infact only a small number of partitions may be being referred by the
> actual query (due to additional filters), and hence these could be run using
> BroadCastHash join.
> The query plan should consider the size of only the referred partitions in
> such cases
