Subject [jira] [Updated] (HDFS-10921) TestDiskspaceQuotaUpdate doesn't wait for NN to get out of safe mode
Date Wed, 26 Oct 2016 21:21:58 GMT

     [ https://issues.apache.org/jira/browse/HDFS-10921?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mingliang Liu updated HDFS-10921:
---------------------------------
       Resolution: Fixed
     Hadoop Flags: Reviewed
    Fix Version/s: 3.0.0-alpha2
                   2.7.4
           Status: Resolved  (was: Patch Available)

Generally I'd prefer a brand-new mini-cluster for each test as it's simpler and clearer. However,
in this case the overhead of creating/destroying a cluster for each case is obvious and is
a concern. The total runtime at my local test machine for individual vs. shared cluster is
58 seconds vs. 37 seconds.

However, using a shared cluster we may have to deal with problems like this. I think the solution
is pretty good. Thanks for the good discussion guys.
