      Description

      Hi,
      I was using 10.0 version before where in I could get this working with my same setup.

      I upgraded to 10.1.9.(Well I didnt really do upgrading process on existing setup yet. But I was doing a poc of this setup before taking upgrade decision).
      My setup has two galera clsuters in two diff datacenters. with 10.1.9 - those two independent galera clusters comes up nicely. I want these two galera clusters to talk to each other using master - master replicaiton.(Two way replication). Forget about two way - I am not even able to establish 1 way replicaiton. The moment - I start slave thread on one of the galera cluster's node. the node crashes - with below error

      This could be because you hit a bug. It is also possible that this binary
      or one of the libraries it was linked against is corrupt, improperly built,
      or misconfigured. This error can also be caused by malfunctioning hardware.

      We will try our best to scrape up some info that will hopefully help
      diagnose the problem, but since we have already crashed,
      something is definitely wrong and this may fail.

      Server version: 10.1.9-MariaDB-1~jessie-log
      key_buffer_size=536870912
      read_buffer_size=2097152
      max_used_connections=1
      max_threads=102
      thread_count=3
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1153038 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
