Subject [jira] [Commented] (HBASE-5320) Create client API to handle HBase maintenance gracefully
Date Thu, 23 Aug 2012 04:22:42 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5320?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13440041#comment-13440041
] 

Lars Hofhansl commented on HBASE-5320:
--------------------------------------

And, yes, generally I think we should create an asynchronous HBase (and ZK!) client. A synchronous
client can be easily layered on top of that, while the reverse is not true.

> When we do HBase cluster maintenance, we typically have to manually stop or disable the
client temporarily. It would be nice to have a way for the client to find out that HBase in
undergoing maintenance through an appropriate API and gracefully handle it on its own.
