[jira] [Updated] (TEZ-400) Change RuntimeTask to handle Input/Output lifecycle

     [ https://issues.apache.org/jira/browse/TEZ-400?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Siddharth Seth updated TEZ-400:
-------------------------------

    Attachment: TEZ-400.1.txt

Adds a LogicalIOProcessorRuntimeTask to manage the lifecycle of a task.

This is supposed to be used by YarnTezDAGChild or the runner. Haven't pulled methods out into an itnerface yet though.

> I/O initialization and teardown should be handled by RuntimeTask. This would involve a fair amount of change to the MR Processors which deal with this internally.
