["Rohini Palaniswamy (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-4411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14376291#comment-14376291 ] 

Rohini Palaniswamy commented on PIG-4411:
-----------------------------------------

Also need to convert mapreduce.map.maxattempts and mapreduce.reduce.maxattempts to TEZ_AM_TASK_MAX_FAILED_ATTEMPTS. In this jira, will turn it on at the AM level.  When TEZ-1233/TEZ-1788 is available will turn it on at the vertex level differentiating map and reduce settings in a separate jira.

> Need to add code in Pig to translate user setting of mapreduce.map/reduce.speculative and enable speculative execution (tez.am.speculation.enabled) in Tez. Need to take this up after TEZ-1788 - Allow vertex level disabling of speculation is done.
