I have just upgraded my nodes to 2.0 from 1.7. I upgraded via RPM package. When I restart my nodes I get the following error:
[2015-11-03 10:13:02,789][ERROR][gateway ] [MASTER_NODE_1] failed to read local state, exiting...
java.lang.IllegalStateException: unable to upgrade the mappings for the index [logstash-2015.10.21], reason: [Field name [basic_constraints.ca] cannot contain '.']
I cannot figure out why I am getting this exception. Did I miss something in the breaking changes?
