1. Is the partition key stored together with data?
No. Partition key becomes the name of the folder, it does not store along with data.

2. When I load data from HCat, is partition key part of output?
Yes. Partition key will be added to the end of the output.

3. When I store data, what if the schema I specified does not match the table definition?
HCatalog will throw exception. This happens when:

  • Column name does not match
  • Column type does not match
  • Column has different order
