Xi Wang commented on AMBARI-11741:
----------------------------------
The original patch is not a sufficient fix, HDFS dashboard will incorrectly
show 'Upgrade not finalized' for around 5 secs when JMX not available, should
show 'n/a' immediately.
Uploaded second patch to fix sufficiently.
> HDFS Dashboard is incorrectly showing 'Upgrade not finalized' when NameNode
> JMX data not available

> When Ambari is not able to get JMX metrics from the NameNode (this is a

> It's showing n/a for most, except "Upgrade status".
> It is incorrectly showing "Upgrade not finalized".
