Hi,

I am fairly new to HCatlog, and hence I was just trying something in hive and HcatLoader in Pig. What I did is, created a view in Hive and then tried to load data by view I created into pig using HcatLoader. But it seems it is not working. I just wanted to confirm that is there any way to do this? I am getting following error when I tried to load view in pig using HcatLoader

events=Load 'ViewName' using org.apache.hcatalog.pig.HCatLoader(); dump events;

When I use any tableName instead of View from Hive, it seems to work. Further it does not give metastore error. As it says successfully connected to metastore at load statement when it comes to dump, it crashes with the following error.

Any Pointers will be helpful.

Thanks, Atul
