Zhe Zhang commented on HDFS-9429:
---------------------------------
Thanks Xiao for the work. {{MiniJournalCluster#waitActive}} LGTM. Regarding
[~jojochuang]'s question: I think the exception is expected if the IPC server
is not up yet. So the logic if catching such an exception and returning false
to {{waitFor}} -- meaning it should keep waiting -- looks OK.
The only question I have is whether we should call {{waitActive}} in all places
using {{MiniJournalCluster}}.

> 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.
