Subject [jira] [Updated] (YARN-161) Yarn Common has multiple compiler warnings for unchecked operations
Date Tue, 16 Oct 2012 16:37:03 GMT

     [ https://issues.apache.org/jira/browse/YARN-161?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Nauroth updated YARN-161:
-------------------------------

    Attachment: YARN-161.patch

This patch corrects the compiler warnings/errors by specifying type parameters explicitly,
so that the types are not raw.  The last line of the diff actually relaxes a type from Iterator<STATE>
to raw Iterator.  This was the cleaner fix, because the logic afterwards doesn't need more
specific type information.  It just needs to call toString on the elements, and all types
have toString.

This patch will get a -1 from Jenkins for lack of new tests.  There are no logic changes here,
and all existing tests pass.

> The warnings are in classes StateMachineFactory, RecordFactoryProvider, RpcFactoryProvider,
and YarnRemoteExceptionFactoryProvider.  OpenJDK 1.6.0_24 actually treats these as compilation
errors, causing the build to fail.
