Subject [jira] [Commented] (PHOENIX-2817) Phoenix-Spark plugin doesn't work in secured env
Date Thu, 21 Apr 2016 10:49:25 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-2817?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15251700#comment-15251700
] 

Gonzalo Herreros commented on PHOENIX-2817:
-------------------------------------------

For people waiting on this fix there is a very simple workaround provided that you use the
default zk port and path.
It's as simple as only listing the the server names "server1,server2" so the plugin builds
the url correctly:
jdbc:phoenix:server1,server2:2181:/hbase

Then the delegation tokens setup by spark-submit take care of security so Phoenix doesn't
need to do anything with principals or keytabs.

The thing I find a bit confusing is that for other tools the zookeeper quorum URL includes
the port and the path, while for Phoenix the zk quorum is just the server list.

> {noformat}
> The reason is the how zkUrl is handled in PhoenixRDD: 
> {noformat}
> config.set(HConstants.ZOOKEEPER_QUORUM, url )
> {noformat}
> At the same time the {{ConnectionUtil.getInputConnection}} expects to see all parameters
(quorum address, port, znodeParent) in different Configuration properties. As the result it
gets default values for port and znodeParent and adds it to the provided url, so the {{PhoenixEmbededDriver.create}}
receives something like that:
> {noformat}
> jdbc:phoenix:quorum:2181:/hbase-secure:2181:/hbase
> {noformat}
> and consider 2 fields as kerberos principal and keytab.
