Subject [jira] [Commented] (YARN-7505) RM REST endpoints generate malformed JSON
Date Thu, 16 Nov 2017 18:30:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-7505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16255742#comment-16255742
] 

Daniel Templeton commented on YARN-7505:
----------------------------------------

Good point.  The two don't play together well, but it should be easy to swap out codehaus
for fasterxml.

I've been digging into what it would take to put all of this under a v2, and it's not as bad
as I thought, but it's still pretty ugly.  At this point I still haven't figured out how to
apply the change to only v2 and not v1, but I'm not done poking at it yet.

> For all endpoints that return DAOs that contain maps, the generated JSON is malformed.
