----------------------------------------
Summary: WebHCat e2e test Pig_HBase_1 and Pig_HBase_2 are failing
with ClassCastException
Key: HIVE-5452
URL: https://issues.apache.org/jira/browse/HIVE-5452
Project: Hive
Issue Type: Bug
Components: WebHCat
Reporter: Deepesh Khandelwal
Assignee: Deepesh Khandelwal
WebHCat e2e test Pig_HBase_1 tries to read data from a table it created using
the org.apache.hcatalog.hbase.HBaseHCatStorageHandler using the hcat loader
org.apache.hive.hcatalog.pig.HCatLoader(). Following is the pig script.
{code}
a = load 'pig_hbase_1' using org.apache.hive.hcatalog.pig.HCatLoader(); store a
into '/user/hcat/out/root-1380933875-pig.conf/Pig_HBase_1_0_benchmark.out';
{code}
Following error is thrown in the log:

The pig script should instead be using the org.apache.hcatalog.pig.HCatLoader()
instead.
