Subject [jira] [Commented] (HBASE-19321) ZKAsyncRegistry ctor would hang when zookeeper cluster is not available
Date Wed, 22 Nov 2017 06:35:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19321?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16262040#comment-16262040

Duo Zhang commented on HBASE-19321:

A temporary workaround is to call blockUntilConnected when constructing ZKAsyncRegistry but
this is not a production level code. 
I already said this is not a production level code, why do you keep asking 'what's the implication
in production scenario', and 'Isn't this short for real scenario'? I can not get your point.
