[jira] [Commented] (TEZ-432) Make JobToken available to inputs / outputs

["Bikas Saha (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TEZ-432?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13766062#comment-13766062 ] 

Bikas Saha commented on TEZ-432:
--------------------------------

Should this be derived from the env var set by the NodeManager? Nodemanager sets the serviceMetadata for the service into the env of the container. There is no need for the AM to send the serviceMetadata to the container.
{code}
     ByteBuffer shuffleMetadata = outputContext
         .getServiceProviderMetaData(ShuffleUtils.SHUFFLE_HANDLER_SERVICE_ID);
-    int shufflePort = ShuffleUtils.deserializeShuffleMetaData(shuffleMetadata);
+    int shufflePort = ShuffleUtils.deserializeShuffleProviderMetaData(shuffleMetadata);
{code}

In either case, the AM does not need to handle shuffle port anymore. TEZ-440.
