Subject [jira] [Commented] (HDFS-14130) Make ZKFC ObserverNode aware
Date Fri, 22 Feb 2019 18:21:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-14130?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16775470#comment-16775470

Chao Sun commented on HDFS-14130:
---------------------------------

Thanks [~shv]. I'm slightly more in favor of the System.in approach because it's more realistic
- curious why it failed but the one in TestDFSHAAdmin didn't. The latest patch looks better
since it reset the {{System.in}} after finish.

The fix itself looks good to me. One minor nit: change {{testverifyObserverState}} to {{testVerifyObserverState}}.
