[jira] [Commented] (YARN-8937) TestLeaderElectorService hangs

["Akira Ajisaka (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-8937?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16677542#comment-16677542 ] 

Akira Ajisaka commented on YARN-8937:
-------------------------------------

Upgrading Curator to 4.0.0 or upper does not fix this issue because if we are using ZK 3.4.x, Curator 2.x is still used for tests.

Upgrading Curator to 4.0.x *and* upgrading ZooKeeper to 3.5.x fix this issue.

Now I'm asking ZooKeeper and Curator community to fix this problem.
