Subject Re: regression in 2.4? YARN severs on secure cluster startup
Date Thu, 30 Jan 2014 10:02:54 GMT
I can confirm that YARN-1600 fixes the YARN problem, so you can upgrade the
YARN binaries without having to patch the yarn-site.xml to get them to
start again.

However, that leaves the need to set the
'dfs.web.authentication.kerberos.principal'
on a secure cluster once you've upgrade -if you hadn't already.

https://issues.apache.org/jira/browse/HDFS-5532 "Enable the webhdfs by
default to support new HDFS web UI"

I think that makes it something to pull up as potentially incompatible,
with the note in CHANGES.TXT -you need to set  'dfs.web.authentication.
kerberos.principal on a secure cluster.

I've stuck my stack trace into the JIRA so it will be searchable
