Hi all,
I'm using Hive 0.12 and running some experiments with the ORC file. The
hdfs block size is 128MB and I was wondering what is the best stripe size
to use. The default one (250MB) is larger than the block size. Is each
stripe splittable or in this case each map task will have to access data
Yes this blog + hive_test should be merged into a jira and then officially
integrated into hive in some way I think.

Basically when you have data like this, it is best to treat the all the
columns as a single string and write a tool to break the entire row apart.
You could use a UDF or a UDTF actually. Look at something like parseUrl...

Matt,
Thanks for the suggestion. Can you please provide more details on what type of
UDAF should I develop ? I have never worked on a UDAF earlier. But would like
to explore it. Any tips on how to proceed.
Thanks,

Let's discuss annual rotation of the PMC chair a bit more. Although I
