ERROR 2135: Received error from store function.Premature EOF: no length prefix available

[pth001]

Hi,

My pig on Tez (to store dataset into a partitioned hive table) throws 
the following exception. What can be wrong? How can I fix it?

filter by query result

[pth001]

Hi,

I am new to pig. First I queried a hive table (x = LOAD 'x' USING 
org.apache.hive.hcatalog.pig.HCatLoader();) and got a single 
record/value. How can I used this single value to filter in another 
query? I hope to get a better performance by filter as soon as possible.

create a pipeline

Hi,

How can I create a pipeline (containing a sequence of pig scripts)?
