Whirr to restart a cluster
Hi All,
Is there any way i can restart hbase cluster using whirr ? Meaning to say I
dnt wanna destroy and re-create the cluster but just to start and stop so
that I dnt lose my data on that those instances..
If I login to those instances and try to stop and start it says pid file is
not found and hbase is not running. So I presume whirr starts and stop with
specific config which are places at different locations ?
Cheers
Akash A;

Thanks Ashok for figuring this out. We should update the bash scripts in
WHIRR-266.

Got it working. ( All stop and start should be run as hadoop user )
1. Change the password of hadoop user ( sudo passwd hadoop )
2. Create hadoop home directories ( from ec2-user as sudo and give hadoop
user permissions )
3. ssh-keygen ( With empty passphrases )
4. copy authorized_keys of ec2-user to /home/hadoop/.ssh
Enjoy:
/usr/local/hbase-<version>/bin/hbase-daemons.sh stop master
/usr/local/hbase-<version>/bin/hbase-daemons.sh start master

yeah I've gone through this before but then SSH has an issue
hbase-daemons.sh stop master
Permission denied (publickey).
Thus I couldn't stop it manually

Are these mostly scripting changes ? I am not well versed with the code
base of Whirr. But If you could point me to the right place I could take
this up for HBase. Should I file a JIRA ?

We are working on this for 0.8.0. See:
https://issues.apache.org/jira/browse/WHIRR-421
This feature is not yet available for HBase but it should be by the time we
make the release.
Also check the following file:
https://github.com/andreisavu/whirr/blob/trunk/services/hbase/src/main/resources/functions/configure_hbase.sh
I think this code snippet is relevant for you:
function start_hbase_daemon() {
if which dpkg &> /dev/null; then
AS_HADOOP="su -s /bin/bash - hadoop -c"
elif which rpm &> /dev/null; then
AS_HADOOP="/sbin/runuser -s /bin/bash - hadoop -c"
fi
$AS_HADOOP "$HBASE_HOME/bin/hbase-daemon.sh start $1"
}
