Hello Michael Brown, Internal Jenkins, Alex Behm,
I'd like you to reexamine a change. Please visit
to look at the new patch set (#9).
Change subject: IMPALA-2013: Reintroduce steps for checking HBase health in
IMPALA-2013: Reintroduce steps for checking HBase health in run-hbase.sh
We used to include a step in run-hbase.sh for calling a python
script that queried Zookeeper to see if the HBase master was up.
The original script was problematic, so we stopped using it during
our mini-cluster HBase start up procedure.
HBase start up issues continue to plague us, however. This patch
reintroduces a Zookeeper check, with the following updates:
- replace the original script with check-hbase-nodes.py
- query the correct node /hbase/master, not just /hbase/rs
- use the python Zookeeper library kazoo, rather than calling
out to the shell and parsing the return string
- since we are moving toward testing on a remote cluster, also
add the capability to pass in the address for the host that
provides the Zookeeper and HBase services
- add an additional check that the HDFS service is running,
because of an edge case where the HBase master can briefly
start without a cluster running.
In addition to the expected tests, this script was also tested
under the conditions of IMPALA-4088, whereby the HBase RegionServer
is running, but the master fails because another listening process
has already taken its TCP port (60010) during startup.
