> 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:
