    Hello Sir/Madam,

    I have configured HDFS on my Ubuntu cluster . Now when I try to implement a Map/Reduce program in it, it is not running because the NameNode automatically becomes inactive in a few seconds. I tried searching many things but could not get any useful information for the same. Please help me in this regard.

    Hi, Sagar,

    There are a few things to check:

    1. What version of HDP are you using?
    2. What do you mean saying ‘NameNode automatically becomes inactive’? Is the namenode process down? Can you please verify?
    3. Please check namenode log or upload namenode log to our ftp site.

    Hope this helps.

    Thanks
