Sometimes they are only meaningful to people who understand how Hadoop works -but you are going to have to learn that anyway. * Some of the log messages include URLs to pages in this wiki. Follow the links -they are there for a reason. - * Search engines are a surprisingly useful way of finding out what an error message machines. Before panicking and sending out messages to all known hadoop mailing lists as well as filing critical-level JIRA issues, why not copy the string from the logs and paste into the search dialog of your search engine of choice -and see what comes up. The discussions on the user list archives are always worth reading, as are any references on stack overflow. + * Search engines are a surprisingly useful way of finding out what an error message machines.
