[jira] [Commented] (YARN-1304) Error starting AM: org.apache.hadoop.security.token.TokenIdentifier: Error reading configuration file

    [ https://issues.apache.org/jira/browse/YARN-1304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13965966#comment-13965966 ] 

Josh Elser commented on YARN-1304:
----------------------------------

Just ran into this one myself. In my case, I had inadvertently updated some hadoop jars after the NM was already running. When an MR went to look at the classpath, some of the jars weren't on local filesystem anymore, and it bailed out.

Restarting the NM and verifying that all hadoop jars were present and readable were sufficient for me to work around this. Probably worthwhile to close this out without any more info.
