Did you execute the pig job with -useHCatalog? It requires to load hcatalog libraries.

Yes, I have load -useHCatalog

I fix the error and can show the result,

but it still have warning "Use "yarn jar" to launch YARN applications."

@WeiHsiang Tseng,

Hi,

I'm facing the same problem. did you resolve it? Thanks.

the problem is that the column "totmiles" in table riskfactor is of type BIGINT while the input for it coming from the "drivermileage" table is of type DOUBLE. So you either have to change the type of the "totmiles" column in "drivermileage" or in "riskfactor". Another option might be a simple cast from DOUBLE to BIGINT. I just recreated the "riskfactor" table using DOUBLE as type for "totmileage"
