-----------------------------------------
Summary: Canary test timesout if there is failed\shutdown
zookeeper node in a quoram
Key: HBASE-15805
URL: https://issues.apache.org/jira/browse/HBASE-15805
Project: HBase
Issue Type: Bug
Components: canary
Affects Versions: 0.98.20
Reporter: Vishal Khandelwal
Fix For: 0.98.20
Canary tools creates HBaseadmin object which which starts a thread to keep
pinging zookeeper on a regular interval. This cause delay when one of the node
in zookeeper is down and test timeouts.
Canary tool is creating HBaseadmin whose isEnabled and tableExists calls
starts a catalog tacker --> retries for zookeeper connection. This zookeeper
(6s) retry happens for multiple times for scanning 390+ region it is causing
lot of sleeps. By removing the failed zookeeper from the test it actually took
not more than 9 sec where it was taking almost 8 mins. Since this is
synchronized call thus for more table this causes the wait and delay in canary
