[jira] [Created] (KAFKA-947) isr-expiration-thread may block LeaderAndIsr request for a relatively long period

Jun Rao created KAFKA-947:
-----------------------------

             Summary: isr-expiration-thread may block LeaderAndIsr request for a relatively long period 
                 Key: KAFKA-947
                 URL: https://issues.apache.org/jira/browse/KAFKA-947
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 0.8.1
            Reporter: Jun Rao
            Assignee: Jun Rao


If there are lots of partitions whose isr needs to be shrank, isr-expiration-thread will hold a long lock on leaderPartitionsLock, which will delay LeaderAndIsr requests.
