Hi all,
Is there any api to retrieve the parameter's column name in GenericUDF?
For example:
Select UDFTEST(columnA,columnB) from test;
I want to get the column names("columnA" and "columnB") in
UDFTEST's initialize function via ObjectInspector but I did not find any
viable solution.
Hi all,

In order to speed up this query since table A and B have lots of data,
another approach is :

Hi all,
I am wondering how to change the fields separator of INSERT OVERWRITE LOCAL
DIRECTORY , does anyone have experience doing this ? thanks!

status of hive(or job progress).I want to get execution progress of queries
from hive?How to do that?Thanks!
Can you provide some references? Thanks very much!

Hi all,
I want to build a website to monitor the execution of queries sent to hive
, is there any way to realize it?
Hi, I meet the same problem once, then I change the amount of imported
columns it works fine. Sometimes blank rows would be generated by sqoop..I
do not actually know what the problem really is..
