Siddharth Seth commented on TEZ-2218:
-------------------------------------
Are there any pre-conditions for this, testing required etc ?
We may be better leaving it off by default - especially for single node
instances, and allow this to be enabled per site. Progress reporting from tasks
being one of the concerns.
> Turn on speculation by default
