[jira] [Created] (YARN-1019) YarnConfiguration validation for local disk path and http addresses.

Omkar Vinit Joshi created YARN-1019:
---------------------------------------

             Summary: YarnConfiguration validation for local disk path and http addresses.
                 Key: YARN-1019
                 URL: https://issues.apache.org/jira/browse/YARN-1019
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Omkar Vinit Joshi
            Priority: Minor


Today we are not validating certain configuration parameters set in yarn-site.xml. 1) Configurations related to paths... such as local-dirs, log-dirs.. Our NM crashes during startup if they are set to relative paths rather than absolute paths. To avoid such failures we can enforce checks (absolute paths) before startup . i.e. before we actually startup...( i.e. directory handler creating directories).
2) Also for all the parameters using "hostname:port" unless we are ok with default port.
