Akira Ajisaka commented on HDFS-15411:
--------------------------------------
It seems that the value of lastBlockReport has been updated between
{code}
String liveNodesInfo = (String) (mbs.getAttribute(mxbeanName,
"LiveNodes"));
{code}
and
{code}
assertEquals(fsn.getLiveNodes(), liveNodesInfo);
{code}
I think the assertion seems too strict.
