[jira] [Created] (SENTRY-1919) Sentry should prevent two snapshots from ebing sent to HDFS

Alexander Kolbasov created SENTRY-1919:
------------------------------------------

             Summary: Sentry should prevent two snapshots from ebing sent to HDFS
                 Key: SENTRY-1919
                 URL: https://issues.apache.org/jira/browse/SENTRY-1919
             Project: Sentry
          Issue Type: Bug
          Components: Sentry
    Affects Versions: 2.0.0
            Reporter: Alexander Kolbasov


When HDFS sync and HDFS HA is enabled it could be possible that two NameNodes will both ask for the full snapshot at the same time. This can double the size of memory needed to serve snapshot and should be prevented.
