Description

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.
