[jira] [Commented] (TEZ-2810) Support for showing allocation delays due to internal preemption

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

    [ https://issues.apache.org/jira/browse/TEZ-2810?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14740004#comment-14740004 ] 

Bikas Saha commented on TEZ-2810:
---------------------------------

AnalyseDAG split into straggler analysis and allocation analysis.
Allocation analysis adds preemption support. Find all preempted attempts in the job. Identify those that were preempted while a critical path attempt was waiting for allocation. Mark that as a potential cause for the preemption.

Drawing critical path handles cases where allocation/launch have not occurred.

Added test for preemption logic.
