DataNode log Error

    Hi,

    I am using Hadoop-1.1.2 and in Datanode log I got following error after every 5 seconds:

    Hi Bhushan ,

    Can you please let us know which version of HDP you are using?

    This error should be harmless for actual HDFS performance. Please see this post:

    Hope this helps,

    Thanks,
    Seth
