Rui Li commented on FLINK-17086:
--------------------------------
[~leiwangouc] Glad to know it worked.
For Orc and Parquet tables, we have vectorized and non-vectorized readers.
Setting "table.exec.hive.fallback-mapred-reader: true" will force use the
non-vectorized reader.
In general, non-vectorized reader provides better compatibility with Hive, but
is less performant than the vectorized one. So I suggest use it only as a
workaround when the vectorized reader doesn't meet your needs. We'll make the
vectorized reader case-insensitive too in the future.
