Subject [jira] [Commented] (ACCUMULO-1794) Add tests that flex Hadoop 2 features
Date Sun, 08 Dec 2013 04:19:36 GMT


Josh Elser commented on ACCUMULO-1794:

>> Can we find namenodes for the namespaces configured?
> This is covered in the current error handling.

Currently the script only checks the namenodes when it goes to agitate the given namespace.
My initial point was that it would be better to validate the namespaces up front once, instead
of every time hdfs-agitator does work. Although, I suppose it would be possible that someone
changes the configuration out from underneath us (standby NN gets bounced)? Either way, just
a passing thought -- not a huge issue.

bq. If Hadoop adds more than 2 namenodes per nameservice in the future

Haha, I didn't realize that :X
