Alan Gates commented on HIVE-17580:
-----------------------------------
I'm +1 on using the SARGs for this, but I think we will have to continue to
provide the current version of get_fields_with_environment_context for
backwards compatibility. So we should find something that works for it as
well. It makes sense to do that first and add a SARGs version of the call
later.
> 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.
