[jira] [Commented] (TEZ-4094) Change Task Interface to use List instead of Concrete ArrayList

    [ https://issues.apache.org/jira/browse/TEZ-4094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17163926#comment-17163926 ] 

Jonathan Turner Eagles commented on TEZ-4094:
---------------------------------------------

[~belugabehr], there has much work to ensure the scalability of tez. By allocating memory space for all attempts up front, we work against that goal.

As to the need for this change (changing from ArrayList to List in this case), it will need some better analysis to demonstrate the value proposition. Currently, I'm leaning toward closing as "Won't Fix"
