[jira] [Created] (IMPALA-9919) Bad Impala Performance after a period of time

Vagelis Nomikos created IMPALA-9919:
---------------------------------------

             Summary: Bad Impala Performance after a period of time
                 Key: IMPALA-9919
                 URL: https://issues.apache.org/jira/browse/IMPALA-9919
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 2.10.0
         Environment: OS: CentOS 6.9
            Reporter: Vagelis Nomikos


Our cluster is consisting of about 60 Impala nodes. After a period of time and after executing some "heavy" queries the performance of the cluster becomes bad and the Impala is not responding after a period of time. We observed that day after day the Impala Resident memory and the running threads of the machine keep growing even if we do not run queries. Everytime we perform an Impala restart everything seems to work fine for a period of time.
