[jira] [Comment Edited] (HIVE-11676) implement metastore API to do file footer PPD

    [ https://issues.apache.org/jira/browse/HIVE-11676?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14944397#comment-14944397 ]

This patch will need a slight modification. If we send stripe boundaries in the PPD result, we don't need to return the footer at all. The rest can be reviewed.

> Need to pass on the expression/sarg, extract column stats from footer (at write time?) and then apply one to the other.
