NameNode can not be started

Hi all,

I have installed all my required services of hadoop using ambari and they are vissible on ambari UI. But i am not able to start any services. I am not able to identify why this error is coming and what should be the resolution for this.

I would be glad if anyone can help me with the resolution of this error.

I was also seeing the same error on one of my test cluster

The error was

 File "/usr/lib/python2.6/site-packages/resource_management/core/sudo.py", line 73, in chmod_extended
    os.chmod(path, attr_to_bitmask(mode, initial_bitmask=st.st_mode)) 

OSError: [Errno 1] Operation not permitted: '/proc/sys'

From Ambari > HDFS > Config I have changed the NameNode directories

From

/hadoop/hdfs/namenode,/proc/sys/fs/hadoop/hdfs/namenode,/proc/sys/kernel/hadoop/hdfs/namenode

To

/hadoop/hdfs/namenode

Above change resolved the issue and namenode started fine

Just ensure that you are using correct hadoop namenode directory path to mitigate such issues

When you will add some security services to your cluster like knox and ranger (In my case it was Knox) it will change the NameNode directory which create the problem.

So revert it back to original will solve the problem.

Thanks Pankaj !!
