> Key: HBASE-27192
> URL: https://issues.apache.org/jira/browse/HBASE-27192
> Project: HBase
> Issue Type: Bug
> Components: test, Zookeeper
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
> Fix For: 2.5.0, 3.0.0-alpha-4, 2.4.14
>
>
> The retry number is only 2, checking the log output, we will fail the request
> within 600ms, which is too small in testMetaMoveDuringClientZkClusterRestart,
> as in this method we will shutdown the client zookeeper, the retry interval
> when updating zookeeper is way more greater, usually several seconds. For
> example
