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

             Summary: Add Metrics for the number of Hive operations waiting for 
compile
                 Key: HIVE-13813
                 URL: https://issues.apache.org/jira/browse/HIVE-13813
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
    Affects Versions: 2.0.0, 1.3.0
            Reporter: Chao Sun
            Assignee: Chao Sun


Currently, without {{hive.driver.parallel.compilation}} introduced in 
HIVE-4239, only one SQL operation can enter the compilation block per HS2 
instance, and all the rest will be blocked. We should add metrics info for the 
number of operations that are blocked.
