Subject [jira] [Commented] (DRILL-3887) Parquet metadata cache not being used
Date Fri, 02 Oct 2015 06:08:26 GMT

    [ https://issues.apache.org/jira/browse/DRILL-3887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14940803#comment-14940803

Steven Phillips commented on DRILL-3887:

It was a detail in the code that I missed. 

I added the field "usedCache", which will show up in the physical plan. There is a unit test
that tests this, and this can also be used by qa for functional testing.

>            Priority: Critical
> The fix for DRILL-3788 causes a directory to be expanded to its list of files early in
the query, and this change causes the ParquetGroupScan to no longer use the parquet metadata
file, even when it is there.
