[jira] [Created] (SENTRY-1806) HDFS update handling shouldn't use linked lists

Alexander Kolbasov created SENTRY-1806:
------------------------------------------

             Summary: HDFS update handling shouldn't use linked lists
                 Key: SENTRY-1806
                 URL: https://issues.apache.org/jira/browse/SENTRY-1806
             Project: Sentry
          Issue Type: Sub-task
          Components: Sentry
    Affects Versions: 1.8.0, sentry-ha-redesign
            Reporter: Alexander Kolbasov
            Assignee: Alexander Kolbasov


The SentryHDFSServiceClientDefaultImpl uses linked lists to represent updates. INstead it should use ArrayList for delta update and singleton for full updates. This will improve memory usage on the HDFS side.
