             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.
