Problems installing pyhs2 in python3 - hive

Question

I am using CentOS 6.5 and want to access a remote hive server. But I am unable to install pyhs2 using pip install pyhs2.
I have installed all the required dependencies:
gcc-c++
python-devel.x86_64
cyrus-sasl-devel.x86_64
But still I get the same error:
Failed building wheel for sasl
Failed to build sasl

Answer 1

This is an issue with Python3 and the dependency SASL. SASL is currently coded for Python2. This is seen with the error 'PyString_AsString not being declared in the scope'.
A short term solution, if possible, would be to use Python2. Long term, either the SASL dependency will need to be updated for Python3 or pyhs2 will need to use a different dependency.

Answer 2

Quick update:
It seems that now the "installation" of this module with pip-Python3 (I tried with 3.5 and 3.6) is possible.
However, even if it installs you won't be able to use it in Python3 because the module has never been ported to such version (for instance, it still uses the "cStringIO" module, which no longer exists in Python3).
Since pyhs2 is no longer maintained (see note in https://github.com/BradRuderman/pyhs2), you're stuck with Python2 or you'd better switch to another tool to connect to HiverServer2.
