Subject [jira] [Commented] (HDFS-12331) Ozone: Mini cluster can't start up on Windows after HDFS-12159
Date Tue, 12 Sep 2017 14:50:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12331?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16163056#comment-16163056

Anu Engineer commented on HDFS-12331:
-------------------------------------

[~linyiqun] Please ignore these tags.  I am going to send out an invite so we can all discuss
these. We are using this to create a set of bugs that we must absolutely work on with priority.
This issue will automatically go away when the next version of Ratis is updated. So the post
merge allows us not to worry about this in the work schedules. That is all. Thanks for asking
though.

> The root cause is that RatiServer instance was newly created in {{OzoneContainer}} after
HDFS-12159 but it can't recognize the path under Windows.
