> HCatalog is ignoring user specified avro schema in the table definition ,
> instead generating its own avro based from hive meta store.
> By generating its own schema will result in mismatch names. For exmple Avro
> fields name are Case Sensitive. By generating it's own schema will result
> in incorrect schema written to the avro file , and result select fail on
> read. And also Even if user specified schema does not allow null , when
> data is written using Hcatalog , it will write a schema that will allow null.
> For example in the table , user specified , all CAPITAL letters in the
> schema , and record name as LINEITEM. The schema should be written as it is.
> Instead Hcatalog ignores it and generated its own avro schema from the hive
> table case.
