[jira] [Commented] (TEZ-1786) Support for speculation of slow tasks

    [ https://issues.apache.org/jira/browse/TEZ-1786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16153027#comment-16153027 ] 

Hitesh Sharma commented on TEZ-1786:
------------------------------------

Hello,

[~bikassaha], I'm trying to understand if the latest versions of Tez 0.9 support speculative execution in any form or not. From the JIRAs it seems that some form of speculative execution exists but there is room for improvement which is being tracked by the open JIRAs. Is my understanding correct here?

Thanks!
