Ashish Thusoo commented on HIVE-645:
------------------------------------
One more thing. Having side effects in the udfs is generally not a good idea
more so because mappers may fail and leave spurious rows may appear in the
target data set specially since each udf invocation is protected through a
transaction instead of the whole chunk of rows being protected through a
transaction.
