@zhouwei0914 This PR is no longer active, please see #344
However here is a quick recap of the issue: It has been relatively easy to
rewrite python-phoenixdb to use requests, however we found out that during
authentication requests-kerberos sends a kerberos OID rather then a SPNEGO OID
for mechanism. There were two workarounds
1. Patch requests-kerberos (was never merged requests-kerberos#115 )
2. A new SPNEGO handler for Avatica that would override Jetty's default
handler (CALCITE-1922)
It turned out that 2 Produced the desired effect that I abandoned the path
of attempting to path requests-kerberos. However in the current PR #344 on top
of Phoenix 5 it appears that this strategy no longer works. See additional
details in later comments in PHOENIX-4688
