> Retry REQUESTTIMEOUT KeeperExceptions from ZK
> ---------------------------------------------
>
> Key: HBASE-25743
> URL: https://issues.apache.org/jira/browse/HBASE-25743
> Project: HBase
> Issue Type: Bug
> Components: Zookeeper
> Affects Versions: 3.0.0-alpha-1, 2.5.0, 2.4.3, 2.3.6
> Reporter: Bharath Vissapragada
> Assignee: Bharath Vissapragada
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.5.0, 2.4.3, 2.3.6
>
>
> Starting ZOOKEEPER-2251, client requests exceeding a timeout can throw a
> KeeperException with REQUESTTIMEOUT opcode set. RecoverableZookeeper doesn't
> transparently retry in such case. This was causing RS aborts when there is a
> flaky ZK quorum member serving slow requests (especially in cases like
> rolling upgrades and such).
