Subject [jira] [Commented] (HBASE-11699) Region servers exclusion list to HMaster.
Date Tue, 12 Aug 2014 19:45:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14094572#comment-14094572

Gomathivinayagam Muthuvinayagam commented on HBASE-11699:
---------------------------------------------------------

I am planning to have the information stored in meta table. I am looking into the metatableaccessor
and other relevant classes.
Probably the rowkey value will be combination of [ [prefix-partial-key] [allow/deny] [hostname]],
and there will be no value for this rowkey. I will scan the included and excluded hosts information
from this information. Let me find out whether it will work.

> Currently HBase does not support adding set of region servers to be in the exclusion
list. So that administrators can prevent accidental startups of some region servers to join
the cluster. There was initially some work done, and it is available in https://issues.apache.org/jira/browse/HBASE-3833.
It was not done after that. 
> I am planning to contribute it as a patch, and I would like to do some improvements as
well. Instead of storing the exclusion entries on a file, I am planning to store it on zookeeper.
Can anyone suggest thoughts on this?
