On 2.0 repair -pr option is not supported together with -local, -hosts or -dc, since it assumes you need to repair all nodes in all DCs and it will throw and error if you try to run with nodetool, so perhaps there's something wrong with range_repair options parsing.
On 2.1 it was added support to simultaneous -pr and -local options on CASSANDRA-7450, so if you need that you can either upgade to 2.1 or backport that to 2.0. 2016-08-10 5:20 GMT-03:00 Anishek Agarwal <anis...@gmail.com>: > Hello, > > We have 2.0.17 cassandra cluster(*DC1*) with a cross dc setup with a > smaller cluster(*DC2*).
