Edward Capriolo commented on HIVE-599:
--------------------------------------
I am not saying that python bindings are a bad idea, but I do not understand
what would be achieved with python that could not be archived by running a
stand alone java program. I read some of the links above it looks like
'langlets' are python apps that abstract input and output steams of external
processes into useful python functions.
Should all the langlets, just be wrappers to 'hivelets'?
For example a 'hivelet' might use the query api to run 'show tables' , or I
might just use the metastore api to read the tables. So in my implementation of
langlets we do most of the heavy lifting in java. This was what I was getting
at when saying 'simple java overlay'.
> Embedded Hive SQL into Python

> While Hive does SQL it would be very powerful to be able to embed that SQL in
> languages like python in such a way that the hive query is also able to
> invoke python functions seemlessly. One possibility is to explore integration
> with Dumbo. Another is to see if the internal map_reduce.py tool can be open
> sourced as a Hive contrib.
> Other thoughts?
