[jira] [Commented] (HBASE-25763) TestRSGroupsWithACL.setupBeforeClass is flaky

["Xiaolin Ha (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-25763?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17320453#comment-17320453 ] 

Xiaolin Ha commented on HBASE-25763:
------------------------------------

FYI [~zhangduo] . I have reproduced the failure, and attached the error logs.

The problem is in SecureTestUtil#getAuthManagerMTimes, it collects the snapshots of variable `mtime` in the auth manager for all the opened regions . But some regions have not opened yet before the check of changed mtimes. So it will always return false by this logic,
{code:java}
for (Map.Entry<AccessController,Long> e: mtimes.entrySet()) {
  if (!oldMTimes.containsKey(e.getKey())) {
    LOG.error("Snapshot of AccessController state does not include instance on region " +
      e.getKey().getRegion().getRegionInfo().getRegionNameAsString());
    // Error out the predicate, we will try again
    return false;
  }
{code}
A new PR has been created.
