Vihang Karajgaonkar commented on HIVE-17580:
--------------------------------------------
latest patch restores {{Category}} enum back into {{ObjectInspector}} since
apparently projects outside Hive also use it directly and moving it out of
ObjectInspector will break stuff. This patch moves the {{ObjectInspector}}
interface to storage-api instead of just moving Category out of it. This way
compatibility is maintained and metastore can still access it without depending
on hive-serde.
> Remove dependency of get_fields_with_environment_context API to serde

> {{get_fields_with_environment_context}} metastore API uses {{Deserializer}}
> class to access the fields metadata for the cases where it is stored along
> with the data files (avro tables). The problem is Deserializer classes is
> defined in hive-serde module and in order to make metastore independent of
> Hive we will have to remove this dependency (atleast we should change it to
> runtime dependency instead of compile time).
> The other option is investigate if we can use SearchArgument to provide this
> functionality.
