"exceeded deadline by N ms" floods logs

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: 3.2.1

      virtualized linux - ec2 - ubuntu

      Description

      More important zookeeper warnings are drown out by the following several times per minute:

      2010-01-12 17:39:57,227:22317(0x4147eb90):ZOO_WARN@zookeeper_interest@1335: Exceeded deadline by 13ms

      Perhaps this is an issue with the way virtualized systems manage gettimeofday results?

      Maybe the current 10ms threshold could be pushed up a bit. I notice that 95% of the messages are below 50ms.

      Is there an obvious configuration change that I can make to fix this?

      config file below:

      1. The number of milliseconds of each tick
        tickTime=2000
      2. The number of ticks that the initial
      3. synchronization phase can take
        initLimit=10
      4. The number of ticks that can pass between
      5. sending a request and getting an acknowledgement
        syncLimit=5
      6. the directory where the snapshot is stored.
        dataDir=/mnt/zookeeper
      7. the port at which the clients will connect
        clientPort=2181

      server.1=hbase.1:2888:3888
      server.2=hbase.2:2888:3888
      server.3=hbase.3:2888:3888
      server.4=hbase.4:2888:3888
      server.5=hbase.5:2888:3888
