Subject Re: Adding replica on solr - 5.50
Date Fri, 15 Apr 2016 00:21:07 GMT
I’m all for finding another way to make something work, but I feel like this is the wrong
advice. 

There are two options:
1) You are doing something wrong. In which case, you should probably invest in figuring out
what.
2) Solr is doing something wrong. In which case, you should probably invest in figuring out
what, and then file a bug so it doesn’t happen to anyone else.

Adding a replica is a pretty basic operation, so whichever option is the case, I feel like
you’ll just encounter other problems down the road if you don’t figure out what’s going
on.

I’d probably start by creating the single-replica collection, and then inspecting the live_nodes
list in Zookeeper to confirm that the (live) node list is actually what you think it is.
