Subject [jira] [Commented] (HBASE-11604) Disable co-locating meta/master by default
Date Tue, 09 Sep 2014 21:50:29 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11604?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14127617#comment-14127617

Jimmy Xiang commented on HBASE-11604:

bq. But ports clash because though the M doesn't have any regions, it is listening on the
RS port?
That's right. If M doesn't listen on the RS port if it doesn't have any regions, will it cause
more confusing?

bq. For pseudo distributed, we need to specify two configs still? What are they?
Besides setting hbase.cluster.distributed to true, hbase.master.wait.on.regionservers.mintostart
needs to be set to 1. I linked HBASE-11575 here, which has a release note about this change.

bq. should we go ahead with this one.
This is ok with me. [~stack], what do you think?

> To avoid possible confusing, it's better to keep the original deployment scheme in 1.0.
ZK-less region assignment is off by default in 1.0 already. We should, by default, not assign
any region to master or backup master.
