Dropbox response (dropbox/PyHive#76):

You should be able to call the poll() method right after the execute method. We actually do this ourselves in our internal dashboarding tool.

For SQLAlchemy you need to get underneath SQLAlchemy's wrapper to the raw pyhive cursor:

result_proxy = engine.execute(query)
cursor = result_proxy.cursor
cursor.poll()

@bkyryliuk, I am unable to see the progress bar for hive datasources, whereas I am able to see the progress bar for presto datasources. My data source is hive://172.31.26.109:10000/staging_db
