Subject [jira] [Commented] (HADOOP-8315) Support SASL-authenticated ZooKeeper in ActiveStandbyElector
Date Wed, 25 Apr 2012 23:16:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13262234#comment-13262234

Patrick Hunt commented on HADOOP-8315:
--------------------------------------

bq. We need to wait for ZK-1437 upstream

Todd afaik this is not the case, you just need to wait until you see SaslAuthenticated. ZOOKEEPER-1437
fixes things in the case where you don't wait.

> Currently, if you try to use SASL-authenticated ZK with the ActiveStandbyElector, you
run into a couple issues:
> 1) We hit ZOOKEEPER-1437 - we need to wait until we see SaslAuthenticated before we can
make any requests
> 2) We currently throw a fatalError when we see the SaslAuthenticated callback on the
connection watcher
> We need to wait for ZK-1437 upstream, and then upgrade to the fixed version for #1. For
#2 we just need to add a case there and ignore it.
