Subject [jira] [Created] (HIVE-8369) SimpleFetchOptimizer needs to re-enable FS caching before scanning dirs

-----------------------------

             Summary: SimpleFetchOptimizer needs to re-enable FS caching before scanning dirs
                 Key: HIVE-8369
                 URL: https://issues.apache.org/jira/browse/HIVE-8369
             Project: Hive
          Issue Type: Bug
          Components: Physical Optimizer
    Affects Versions: 0.14.0
            Reporter: Gopal V


SimpleFetchOptimizer spends a lot of CPU within itself because hive disables HDFS fs caching
(fs.hdfs.impl.disable.cache).

SimpleFetchOptimizer needs a revisit for its optimization rules, along with a fix for this
case.
