The namenode log for a Hadoop-0.20 installation contains this error message:
"/var/lib/hadoop-0.20/cache/hadoop/dfs/name in in an inconsistent state".
This directory does not exist and I would like to understand why this
particular directory name is required (not what the directory is used for,
but why this particular directory name). The *-site.xml files are below (IP
addresses have been masked).
Thanks in advance for your help.
