Description

If OrcRawRecordMerger#close is called before fully reading an orc file, the primary reader is not closed.

The primary reader is assigned using readers.pollFirstEntry() which deletes the reader from readers, and currently the OrcRawRecordMerger#close method only closes readers in the map.
