Subject [jira] Created: (CHUKWA-563) Collector Crashes when HBase is not started
Date Fri, 03 Dec 2010 19:33:11 GMT
Collector Crashes when HBase is not started
-------------------------------------------

                 Key: CHUKWA-563
                 URL: https://issues.apache.org/jira/browse/CHUKWA-563
             Project: Chukwa
          Issue Type: Bug
          Components: data collection
    Affects Versions: 0.4.0
         Environment: Ubuntu 8.04
            Reporter: Ahmed Fathalla
             Fix For: 0.5.0


When using HBaseWriter, collectors crash if they start and do not find HBase running. Collectors also crash if HBase is running and Tables are not found

Here are the exceptions in collector.log when HBase is not running
