Subject [jira] [Commented] (HBASE-6775) Use ZK.multi when available for HBASE-6710 0.92/0.94 compatibility fix

    [ https://issues.apache.org/jira/browse/HBASE-6775?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13485550#comment-13485550

stack commented on HBASE-6775:

Config is a bad idea IMO.  We have enough cryptic config. already.

One thought I had was that you could connect to an ensemble member that supported multi but
another member might not.  If your session moves, I don't believe the client is told so you
could do a multi against an older ensemble member.  This might be a bit on the exotic side
(different ensemble versions is probably temporary condition while ensemble is being updated)

>             Project: HBase
>          Issue Type: Improvement
>          Components: Zookeeper
>    Affects Versions: 0.94.2
>            Reporter: Gregory Chanan
>            Assignee: Gregory Chanan
>            Priority: Minor
>             Fix For: 0.94.4
> HBASE-6710 fixed a 0.92/0.94 compatibility issue by writing two znodes in different formats.
> If a ZK failure occurs between the writing of the two znodes, strange behavior can result.
> This issue is a reminder to change these two ZK writes to use ZK.multi when we require
ZK 3.4+.
