[jira] [Commented] (TEZ-2959) Make InputContext available to InputFormats

    [ https://issues.apache.org/jira/browse/TEZ-2959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15047778#comment-15047778 ] 

Siddharth Seth commented on TEZ-2959:
-------------------------------------

Not sure InputEstimator (SplitSizeEstimator?) and this new interface should be merged. SplitSizeEstimator isn't necessarily implemented by an InputFormat - and there can be different split size strategies for the same InputFormat. The location provider was kept separate for the same reason.

> Currently an InputFormat can only be provided with a Configuration instance, which very often is not adequate.
