java.io.IOException: Deserialization error: org.apache.hcatalog.data.schema.HCatSchema
Hi All,
I'm currently integrating Pig with HCatalog & then trying to run the pig
scripts. I'm using cloudera CDH 4.4.0 with pig-0.11.0+33, hive-0.10.0+198
and hcatalog-0.5.0+13.
When I use pig -useHCatalog to run my pig scripts, everything works fine.
But when I try to launch the pig scripts using PigServer (to run pig from
java), I get the following exception. please note that I don't have any
problems running normal pig scripts with PigServer. When I want to use
HCatalog and load the table using org.apache.hcatalog.pig.HCatLoader(), i
get this exception. Pls let me know if anybody has any idea to get around
the issue.

Hi Nitin,
All the required JARS(hadoop,hive,hcatalog) are in the classpath of the Pig
script submission code using PigServer.
There is already a JIRA (https://issues.apache.org/jira/browse/PIG-2532) on
this issue & it is currently in the "resolved" state for the pig version
that im using (pig 0.11). But I'm still getting the issue.
I looked at the source code and found that the suggested fix is not
available in either 0.11 or 0.12. Any suggestions?
Regards,
Prasad

Can you try registering the jar inside your script
