Yin Huai created SPARK-7713:
-------------------------------
Summary: Use shared broadcast hadoop conf for partitioned table
scan.
Key: SPARK-7713
URL: https://issues.apache.org/jira/browse/SPARK-7713
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.4.0
Reporter: Yin Huai
Assignee: Yin Huai
Priority: Blocker
While debugging SPARK-7673, we also found that we are broadcasting a hadoop
conf for every Partition (backed by a Hadoop RDD). It also causes the
performance regression of compiling a query involving a large number of
partitions.
