Xiao Chen updated HDFS-9429:
----------------------------
Attachment: HDFS-9429.001.patch
It seems to me that the root cause is there's no wait-for-active mechanism for
journal nodes in {{MinijournalCluster}}.
Attached patch 1 to add the {{waitActive}} method.
Also, the failures are very hard to reproduce, since the rpc race has to be
very exact. I'm not sure how to programmatically reproduce them yet....
Any feedback/comments are high appreciated.

> I have seen this fail a handful of times for {{testMetaSave}}, but from my
> understanding this is from {{setUpHaCluster}} so theoretically it could fail
> for any cases in the class.
