FAQ
Hello, I've used your cloudera manager to install YARN, zookeeper, flume
and of course hadoop on clean ubuntu 12.04.
But I am facing a problem with persmissions although I've change the
mountpoint for namenode "/" from newly created "/hdfs"

I still get same error in logs :
/var/log/hadoop-hdfs# tail -f hadoop-cmf-hdfs1-NAMENODE-userver.log.out

2012-11-27 11:42:25,528 ERROR
