E.g. permission denied, quota overage, etc. The major contributing factor in slow down is the long namenode log message, which includes full stack trace. > Previously similar issues involving safe mode and standby node have been addressed and we can extend it to suppress logging stack traces for configured list of exception classes. -- This message is automatically generated by JIRA.
