[jira] [Created] (SPARK-9743) Scanning a HadoopFsRelation shouldn't requrire refreshing

Cheng Lian created SPARK-9743:
---------------------------------

             Summary: Scanning a HadoopFsRelation shouldn't requrire refreshing
                 Key: SPARK-9743
                 URL: https://issues.apache.org/jira/browse/SPARK-9743
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.5.0
            Reporter: Cheng Lian
            Assignee: Cheng Lian
            Priority: Blocker


PR #7969 added {{HadoopFsRelation.refresh()}} calls in {{DataSourceStrategy}} to make test case {{InsertSuite.save directly to the path of a JSON table}} pass. However, this forces every {{HadoopFsRelation}} table scan to do a refreshing, which can be super expensive for tables with large number of partitions.
