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.
> Support for speculative execution
