Cheng Lian created SPARK-9783:
---------------------------------
Summary: Use SqlNewHadoopRDD in JSONRelation to eliminate extra
refresh() call
Key: SPARK-9783
URL: https://issues.apache.org/jira/browse/SPARK-9783
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.5.0
Environment: PR #8035 made a quick fix for SPARK-9743 by introducing
an extra {{refresh()}} call in {{JSONRelation.buildScan}}. Obviously it hurts
performance. To overcome this, we can use {{SqlNewHadoopRDD}} there and
override {{listStatus()}} to inject cached {{FileStatus}} instances, similar as
what we did in {{ParquetRelation}}.
