> {{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.
