[jira] [Created] (HIVE-18034) Improving logging with HoS executors spend lots of time in GC

Sahil Takiar created HIVE-18034:
-----------------------------------

             Summary: Improving logging with HoS executors spend lots of time in GC
                 Key: HIVE-18034
                 URL: https://issues.apache.org/jira/browse/HIVE-18034
             Project: Hive
          Issue Type: Sub-task
          Components: Spark
            Reporter: Sahil Takiar


There are times when Spark will spend lots of time doing GC. The Spark History UI shows a bunch of red flags when too much time is spent in GC. It would be nice if those warnings are propagated to Hive.
