> 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")
>     
>
