I get less issues with Pig 0.9.2 but still some. It seems to depend on the script too. I have less issues if i change the script to get only 1 job created, ie when I use 1 dump instead of 2. FYI, I have only 3 rows

Regards

I just started moving our scripts to Pig 0.11.1 from 0.9.2 and I see the same issue - about 75-80% time it fails. So I'm not moving :-/. 

I am using OSX + Oracle Java7 and CassandraStorage, but I did not see any difference between CassandraStorage and CqlStorage.

Cassandra 1.2.9, though 1.1.10 seemed to have the same symptoms.

(Also, ?widerows=true seems to cause a NullPointerExeption in ByteByfferUtil.toString().  So not a very successful evening yesterday.)

Hi,

I get a lot of exceptions when using Pig scripts over Cassandra. I have to launch them again and again until they work. You can find a sample of the stacks when it works (twice) and when it fails (3 times) at http://pastebin.com/yWsTHbix. I use the following sample script (there are only a few lines) :

data = LOAD 'cql://ks1/lc' USING CqlStorage();
describe data;
dump data;
rows  = FOREACH data GENERATE filtre;
dump rows;
describe rows;

any idea or a way to get ride of them ?
