Namit Jain commented on HIVE-457:
---------------------------------
Yes, it is possible to do so via the configuration variable:
hive.script.recordreader.
Infact, there is another reader which we support: TypedBytesRecordReader.
The new paramter that you are adding should not be specific to
TextRecordReader, but should be general to any recordreader.
Maybe, it should be named:
set hive.record.reader.max.length=10485760;
and all recordreaders should be modified to take care of that.
> ScriptOperator should NOT cache all data in stderr

> this causes Hive to go out-of-memory.
> We should directly output the data from stderr without caching it.
