Hello, newbie here.
Currently we are using Cassandra v2.2.1 (two DCs, naming them DC1, DC2,
respectively), and recently we have two issues:
1. Cannot adding new node due to CASSANDRA-10961
2. Cannot repair node, due to CASSANDRA-10501
We learned that we can do rolling upgrade, since we are only
should do that before you upgrade the first node,
