One of my vm hosting hbaseMaster is down and not able to recover. So we start hbase master on another box (manually not from ambari web). I am trying to remove the machine on ambari web, it shows
This host cannot be deleted since it has the following master components:
To delete this host, you must first move all the master components listed above to another host.
On hbase service page it shows:
HBase Master Heartbeat lost…
Active HBase Master Started
HBase Master Unknown
How can i remove it from ambari-master?
Another problem is we upgrade to ambari 1.4.4 for this changing master feature. However, the ambari master become really slow. Top shows high cpu usage. It did not act this way when we were on 1.2.3 nor 1.2.5.
Our hadoop stack is on HDP-1.3.0
