Re: Directory /tmp/hadoop-root/dfs/name is in an inconsistent state: storage directory DOES NOT exist or is NOT accesible

[Eric Sammer <es...@cloudera.com>]

Normally this is due to the machine having been rebooted and /tmp
being cleared out. You do not want to leave the Hadoop name node or
data node storage in /tmp for this reason. Make sure you properly
configure dfs.name.dir and dfs.data.dir to point to directories
outside of /tmp and other directories that may be cleared on boot.

The quick setup guide is really just to help you start experimenting
with Hadoop. For setting up a cluster for any real use, you'll want to
follow the next guide - Cluster Setup -
