------------------------------------------------
Summary: Fix possible NPE/ClassCastException in Stats IT tests
Key: PHOENIX-4495
URL: https://issues.apache.org/jira/browse/PHOENIX-4495
Project: Phoenix
Issue Type: Sub-task
Reporter: Rajeshbabu Chintaguntla
Assignee: Rajeshbabu Chintaguntla
Fix For: 5.0.0
Here are the following tests failing while checking whether stats enabled or
not. To check it we try to pick a proper region but some times we may get wrong
region like system table region or meta region from the RS online regions for
which stats won't be enabled. So we need to pick the right region to check for
it.
