[jira] [Created] (HBASE-25743) Retry REQUESTTIMEOUT KeeperExceptions from ZK

Bharath Vissapragada created HBASE-25743:
--------------------------------------------

             Summary: 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, 1.7.0, 2.5.0, 2.4.3, 2.3.6
            Reporter: Bharath Vissapragada
            Assignee: Bharath Vissapragada


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).
