[jira] [Commented] (TEZ-709) LocalFetcher for the Uber-mode
[ https://issues.apache.org/jira/browse/TEZ-709?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14078987#comment-14078987 ]
Chen He commented on TEZ-709:
-----------------------------
In current Local Mode, there is no NodeManager which provides ShuffleHandler services for data shuffling. We need a way to get the information about where to get the previous vertices' intermediate output.

> In this sub-task, we will focus on writing a LocalFetcher that is in charge of getting output from LocalContainerLauncher and feeding it for the next vertex. After this sub-task, the Uber-mode should be able to run multiple vertex DAG.
