Question

I am using hive-0.12.0,pig-0.12.0,mysql-5.6 and hadoop-1.2.1 in pseudo distribution mode.

I configured PIG_CLASSPATH etc.. details according to the link, https://cwiki.apache.org/confluence/display/Hive/HCatalog+LoadStore

When I try to load a table created in hive into pig using HCatloader, it is giving the Java heap space error.

The details are as follows:

hive.metastore - Trying to connect to metastore with URI thrift://127.0.0.1:3306 2014-04-11 01:12:36,432 [main] INFO hive.metastore - Waiting 1 seconds before next connection attempt. 2014-04-11 01:12:37,432 [main] INFO hive.metastore - Connected to metastore. 2014-04-11 01:12:37,785 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2998: Unhandled internal error. Java heap space Details at logfile: /home/aphadoop/pig_1397158893348.log

Has anybody encountered the same error and solved it?

Please let me know.
