Subject [jira] [Commented] (HAMA-495) Resource management
Date Sun, 26 Feb 2012 13:28:48 GMT


Thomas Jungblut commented on HAMA-495:

I think that ZK handles its path on disk separately than the name of the znode paths. I haven't
faced any issues yet with the normal slashes. However the backslashes make the testcase fail.

bq.The original problem seems to stem from the hard coded path "/monitor/groom_lab01_61000/metrics/jvm".
Running on Windows os, the StringTokeinizer's delimiter becomes backslash, hence the count
is 1.

Yes. We can change the "/" in ZKUtils to File.separator. But then we should retrieve the ZK
paths through the utility which uses the separator. Otherwise we end up with n-separators
and y-paths.

> HAMA-363 provides a way to access to cluster status. Some additional features, such as
federation, are required so the system can have better coordination, and the master would
have ideas about the whole system.
