Review Comment:
This is added as a fix to many failed CI tests that happened without this
fix.
Hive implements its own TreeReaderFactory. In ORC project, ORC-1060 -
"Reduce memory usage when vectorized reading dictionary string encoding
columns" introduced changes to StringDictionaryTreeReader which were causing
exceptions in Hive EncodedTreeReaderFactory when attempting to upgrade to ORC
1.8.1. To handle that I added changes to Hive's EncodedTreeReaderFactory to use
StringDictionaryTreeReader version as without ORC-1060.
