Was getting this issue in Airflow trying to use HiveServer2Hook:     ImportError: cannot import name TFrozenDict   And figured it might be related to this pip warning:     impyla 0.14.1 has requirement thrift<=0.9.3, but you'll have thrift 0.11.0 which is incompatible.   So I adjusted the thrift and impyla installs as indicated and now HiveServer2Hook works (and HiveOperator still works)--both of which are using kerberos beeline connections.   Thanks for posting the fix.   ...
