Sounds like a commons-codec version conflict. Tez is using commons-codec

Hi,
I tried to run pig on TEZ>
pig -Dpig.additional.jars=... -useHCatalog -x TEZ load_u.pig
But I got an exception>

It seems the problem is from commons-codec-*.
Hi,
I have a hive table with a column which was changed its name. Pig is not
able to load data from this column, it is all empty.
Any ideas how to fix it?

Hi,
I am new to pig. I am using pig version 0.12. I found an unexpected
behaviour from left join on multiple columns as listed below

Hi,
I have the following data
(2009-09-09,2,1,{(70)},{(80)},{(90)})
(2010-10-10,2,12,{(71),(75)},{(81),(85)},{(91),(95)})
(2012-12-12,2,9,{(76),(77),(78)},{(86),(87),(88)},{(96),(97),(98)})
which is in the format
{date: chararray, zone: int, z: int, uTmp: {(varvalue: int)}, vTmp:
{(varvalue:
ot;11 ").
Ultimately, you can read the z column as chararray and process it with udf.
This will give you chance to log the faulty record.
Tell if any of this removed the problem.

Hi,
I am using HCatLoader to load data from a table (existing in hive).
A = load 'rwf_data' USING org.apache.hcatalog.pig.HCatLoader();
describe A;
I got Error 1115: Table not found : ...
It is weird. Any suggestions on this? Thanks

Hi,
Is it possible to store results in to a file with determined filename,
instead of part-r-0? How to do that?

Hi,
From the schema
C: {group: (int,int,int),{(varvalue: {t: (varname: chararray,shape:

I would like to get
{int,int,int,(varname,shape)}, where there are multiple varname and
shape value of each varname.
How can I write the pig script to generate that?

Hi,
I wrote a custom InputFormat. When I ran the pig script Load function
using this InputFormat, the number of InputSplit = 16, but there was
only 2 map tasks handling these splits. Apparently the no. of map tasks
= the no. of input files.
Does the number of Map task not correspond to the n
