Is there any way I can prevent Hbase to allocate regions to
particular region servers?
Without switching off the balancer, is there any way I can mark certain hbase
region servers from getting the regions from the HBase master?
Thanks,

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.

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.
Thanks,

Hi Gomes,
Could you please share with us why would you need this behavior?
