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

             Summary: Conditional error in SENTRY-1931 results in sending two snapshots at the same time
                 Key: SENTRY-1946
                 URL: https://issues.apache.org/jira/browse/SENTRY-1946
             Project: Sentry
          Issue Type: Bug
    Affects Versions: 2.0.0
            Reporter: Vamsee Yarlagadda
            Assignee: Vamsee Yarlagadda


As part of SENTRY-1931, we added check not to send two NN snaphsots at the same time. But because of a conditional typo, it results in sending back two snapshots.

{code}
    // If another paths updates request is in progress by another HDFS NameNode, then we
    // return an empty image for now to avoid a large memory consumption
    if (pathsRetrieverBusy.compareAndSet(false, true)) {
      LOGGER.debug("PATHS updates are not available because another request is in progress.");
      return Collections.emptyList();
    }
{code}
