Thank you Jeff!
I will set the consistency / update system_auth too and let you know how it
went by!
In between did you ment to update system_auth.roles table?

> 3.7.0 and Python Driver 3.7 using Python 2.7.11.
> OS: Red Hat Enterprise Linux 6.x x64,
> RAM :8GB
> DISK :210GB
> Cores: 2
> Java 1.8.0_73 JRE

> In our C* cluster we are using the latest Cassandra 3.7.0 (datastax-ddc.3.70)
> with Python driver 3.7. Trying to insert 2 million row or more data into the
> database, but sometimes we are getting "Null pointer Exception".
> We are using Python 2.7.11 and Java 1.8.0_73 in the Cassandra nodes and in
> the client its Python 2.7.12.
