Steps to reproduce

I hive use pip install pyhive Requirement already satisfied: pyhive in /usr/lib/python2.7/site-packages (0.5.1) Requirement already satisfied: future in /usr/lib/python2.7/site-packages (from pyhive) (0.16.0)

And my SQLAlchemy URI : jdbc+hive://qing-hadoop-master-srv1:10000/hive

What should I do to solve this problem Beside, impala databases can not be connected either with SQLAlchemy URI : impala://qing-hadoop-master-srv2:26000/test?auth_mechanism=PLAIN&password=impala&user=impala

truely some mis-understanding here in manual there is an example of using " jdbc+hive:// " as prefix of uri

but actucully just " hive:// " is needed for hive datasource, otherwise error will be prompted like posted. need to correct the manual i think ?
