Issues adding RegionServers to datanodes

[#1]

Hello, I just installed Hbase RegionServers to 2 of my datanodes. I'm getting the following error when I start them on HDP 3.0:

esource_management.core.exceptions.ExecutionFailed: Execution of '/usr/hdp/current/hbase-regionserver/bin/hbase-daemon.sh --config /usr/hdp/current/hbase-regionserver/conf start regionserver' returned 127. -bash: /usr/hdp/current/hbase-regionserver/bin/hbase-daemon.sh: No such file or directory

What am I missing?

I installed them through Ambari.

I think the issue is with a bad hbase-client install. What is the yum install arg to reinstall that?

In ambari UI --> Hosts (Tab) --> Specific Host link --> Install Clients button should install the clients.

However you can try the following command manually on the problematic host to see if it fixes your issue:

# yum reinstall hbase* -y

.

After the reinstall you should see the following Symlink & Directories:

# ls -l /usr/hdp/current/hbase-regionserver
lrwxrwxrwx. 1 root root 27 Jul 21 08:14 /usr/hdp/current/hbase-regionserver -> /usr/hdp/3.0.0.0-1634/hbase

.

and

# ls -l /usr/hdp/3.0.0.0-1634/hbase
total 20
