Actually SREs in my team, sometimes accidentally bring a region server, even though those region servers are not supposed to join the cluster. Also when they bootstrap a new region server, they disable balancer for a long time, I dont want them to disable for a long period of time. I am just wondering whether I can explicitly ask master server to not include certain region servers for region allocation, even if those region servers accidentally join the pool.
At the moment, HBase does not supply/use any include/exclude lists like HDFS does. Without security enabled, anyone starting an RS daemon would be able to join into the cluster.
For the include/exclude feature, you can track the JIRA HBASE-3833.
