[jira] [Commented] (TEZ-1272) Change YARNRunner to make use of EdgeConfigurations

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

    [ https://issues.apache.org/jira/browse/TEZ-1272?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14059562#comment-14059562 ] 

Bikas Saha commented on TEZ-1272:
---------------------------------

For the following replacement.
{code}-    MultiStageMRConfToTezTranslator.translateVertexConfToTez(finalReduceConf,
-        iReduceStageConf);
+    MRHelpers.translateVertexConfToTez(finalReduceConf);{code}
The new method is not calling the following and this actually does something regardless of predecessorConf. So the new code may be missing that. I am guessing you are doing that deliberately. Mind describing the reasoning?
{code}    translateMultiStageWithPredecessor(vertexConf, predecessorConf) {code}

How did this ever work?
{code}-    registerMRToRuntimeKeyTranslation(TezJobConfig.TEZ_CREDENTIALS_PATH, MRJobConfig.MAPREDUCE_JOB_CREDENTIALS_BINARY);
+    registerMRToRuntimeKeyTranslation(MRJobConfig.MAPREDUCE_JOB_CREDENTIALS_BINARY, TezJobConfig.TEZ_CREDENTIALS_PATH);
{code}

This one and others like it, there is probably no need to INTERMEDIATE in the name, right? e.g. OnFileUnorderedOuput could write final output if so desired?
{code}TEZ_RUNTIME_INTERMEDIATE_INPUT_COMPRESS_CODEC{code}

Orthogonally, does OrderedPartitionedKVEdgeConfigurator sound better than OrderedPartitionedKVEdgeConfiguration. Reasons, its the entity that configures instead of being the configuration itself. It actually does more like create edge properties. And finally, it disconnects the name from Configuration.

Looks good.
