Subject cdcr replication of new collection doesn't replicate
Date Fri, 26 Jan 2018 19:29:50 GMT
We have just upgraded our QA solr clouds to 7.2.0
We have 3 solr clouds. collections in the first cloud replicate to the
other 2

For existing collections which we upgraded in place using the lucene index
upgrade tool seem to behave correctly data written to collections in the
first environment replicates to the other 2

We created a new collection has 2 shards each with 2 replicas. The new
collection uses tlog replicas instead of NRT replicas.

We configured CDCR similarly to other collections so that writes to the
first are sent to the other 2 clouds. However, we never see data appear in
the target collections.
We do see tlog files appear, and I can see cdcr update messages in the
logs, but none of the cores ever get any data in them. So the tlogs
accumulate but are never loaded into the target collections

This doesn't seem correct.

I'm at a loss as to what to do next. We will probably copy the index files
from the one collection to the other two collections directly, but
shouldn't cdcr be sending the data?

Does cdcr work with tlog replicas?
