Re: Hadoop 2.0.0 stopping itself
The general@ mailing list is NOT for end-user questions and
discussion. Please use the user@hadoop.apache.org mailing list for
such issues.
Please also read http://hadoop.apache.org/mailing_lists.html prior to
posting emails here.
As to your problem, you will need to look at your logs to determine
why the service crashes. It is likely that the NameNode is not
starting up due to missing data or non-formatting, but you will get a
proper precise reason by looking for a FATAL error in your master
service logs.
