Subject Re: Hadoop 2.2.0 from source configuration
Date Tue, 03 Dec 2013 18:37:16 GMT
I did that more than once, I just retry it from the beginning. I zapped the
directories and recreated them with hdfs namenode -format and restarted
HDFS and I am still getting the very same error.

I have posted previously the report. Is there anything in this report that
indicates I am not having enough free space somewhere? That's the only
thing I can see may cause this problem after everything I read on the
subject. I am new to Hadoop and I just want to setup a standalone node for
starting to experiment a while with it before going ahead with a complete
cluster.

I repost the report for convenience:
