@agl29 I have not removed it and nothing seem to have crashed this far. We have these install_aliases() at several places in our code base. We need to see if we really need them anymore.

I guess we don't need them, may be it was required for python2 based Hue.

The problem is that connector based query execution is not able to reuse session to fetch results. The frontend is sending the correct session_id but our session fetching logic got broken when the computes was implemented. we are now looking for the session_type from compute['name'] for computes, connector['name'] for connector and then snippets['type'] for old config file based hive/impala sessions. A related change is to make use of session for get_log and check_status calls if the frontend is sending it.

Rest is some ruff and other refactoring.
