----------------------------------------
Summary: RegionServer Upgrade verification is not case sensitive
Key: AMBARI-13452
URL: https://issues.apache.org/jira/browse/AMBARI-13452
Project: Ambari
Issue Type: Bug
Reporter: Andrew Onischuk
Assignee: Andrew Onischuk
Fix For: 2.1.3
Reference . During RU, there was an issue when upgrading RegionServers, in
that the check for RS being up was reporting failed. The output of the hbase
shell command was returning host names in uppercase, where Ambari used lower
case names for the hostname (and check). The following commented codes shows
the problem:
In common-services/HBASE/0.96.0.2.0/package/scripts/upgrade.py:
def post_regionserver(env):
import params
env.set_params(params)
check_cmd = "echo 'status \"simple\"' | {0}
shell".format(params.hbase_cmd)
exec_cmd = "{0} {1}".format(params.kinit_cmd, check_cmd)
call_and_match(exec_cmd, params.hbase_user, params.hostname.lower() +
":") # hostname is lower case already
@retry(times=15, sleep_time=2, err_class=Fail)
def call_and_match(cmd, user, regex):
code, out = shell.call(cmd, user=user) # out contains hostnames
capitalized
if not (out and re.search(regex, out)):
raise Fail("Could not verify RS available")
