Rui Li commented on HIVE-8017:
------------------------------
Hi [~xuefuz] I quickly checked the latest failures and I think they are caused
by the {{-- SORT_BEFORE_DIFF}} label. The diff is mainly something like:
{noformat}
> POSTHOOK: query: CREATE TABLE dest_g1(key INT, value DOUBLE) STORED AS
> TEXTFILE
366d362
< POSTHOOK: query: -- SORT_BEFORE_DIFF
375a372
> PREHOOK: query: CREATE TABLE dest_g1(key INT, value DOUBLE) STORED AS TEXTFILE
379d375
< PREHOOK: query: -- SORT_BEFORE_DIFF
{noformat}
There's no diff in the results.
> Use HiveKey instead of BytesWritable as key type of the pair RDD [Spark

> HiveKey should be used as the key type because it holds the hash code for
> partitioning. While BytesWritable serves partitioning well for simple cases,
> we have to use {{HiveKey.hashCode}} for more complicated ones, e.g. join,
> bucketed table, etc.
