---------------------------------------
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.
