Subject [jira] [Commented] (HBASE-12706) Support multiple port numbers in ZK quorum string
Date Wed, 04 Mar 2015 19:36:38 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12706?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14347428#comment-14347428

Enis Soztutar commented on HBASE-12706:
---------------------------------------

bq.  I mentioned that we could document the 2 formats (old way and new way) as supported format
- internally, we can keep my current implementation (the confusing s1:p1, s2:p2, s3:p3:/hbase
input would be the same as s1:p1, s2:p2, s3:p3:p3:/hbase - even the input is not supported,
it would work as expected).
Yes, your patch supports parsing both formats. But we are also generating cluster keys in
the format: {{s1:p1,s2:p2,s3:p3:p3:/hbase}} which is not what we want I think (see all users
of ZKUtil.getZooKeeperClusterKey()). Parsing both forms should be fine, but we should ideally
be generating only the format {{s1:p1,s2:p2,s3:p3:/hbase}} in getZooKeeperClusterKey() method.

> HBase does not allow the zk quorum string to contain port numbers in this format:
> {noformat}
> hostname1:port1,hostname2:port2,hostname3:port3
> {noformat}
> Instead it expects the string to be in this format:
> {noformat}
> hostname1,hostname2,hostname3:port3
> {noformat}
> And port 3 is used for all the client ports. We should flex the parsing so that both
forms are accepted.
> A sample exception:
> {code}
> java.io.IOException: Cluster key passed host1:2181,host2:2181,host3:2181,host4:2181,host5:2181:2181:/hbase
is invalid, the format should be:hbase.zookeeper.quorum:hbase.zookeeper.client.port:zookeeper.znode.parent
