Subject No space when running a hadoop job
Date Fri, 26 Sep 2014 14:37:09 GMT

I am facing some space issue when I saving file into HDFS and/or running map
reduce job.

root@nn:~# df -h

Filesystem                                       Size  Used Avail Use%

/dev/xvda2                                       5.9G  5.9G     0 100% /

/dev/xvda4                                       7.9G  147M  7.4G   2% /mnt  198G  108G   75G  59%
/groups/ch-geni-net/Hadoop-NET               198G  108G   75G  59%


I can see there is no space left on /dev/xvda2.

How can I make hadoop to see newly mounted /dev/xvda4 ? Or do I need to move
the file manually from /dev/xvda2 to xvda4 ?

Thanks & Regards,
