I'm working on my first setup of CDCR, and I'm seeing the same "The log reader
for target collection {collection name} is not initialised" as you saw.
It looks like you're creating collections on a regular basis, but for me, I
create it one time and never again. I've been creating the collection first
from defaults and then applying the CDCR-aware solrconfig changes afterward. It
sounds like maybe I need to create the configset in ZK first, then create the
collections, first on the Target and then on the Source, and I should be good?

Subject: Re: CDCR - how to deal with the transaction log files
glad to hear you found your solution! I have been combing over this post and
others on this discussion board many times and have tried so many tweaks to
configuration, order of steps, etc, all with absolutely no success in getting
the Source cluster tlogs to delete. So incredibly frustrating. If anyone has
other pearls of wisdom I'd love some advice. Quick hits on what I've tried:
- solrconfig exactly like Sean's (target and source respectively) expect no
autoSoftCommit
- I am also calling cdcr?action=DISABLEBUFFER (on source as well as on
target) explicitly before starting since the config setting of
defaultState=disabled doesn't seem to work
- when I create the collection on source first, I get the warning "The log
reader for target collection {collection name} is not initialised". When I
reverse the order (create the collection on target first), no such warning
- tlogs replicate as expected, hard commits on both target and source cause
tlogs to rollover, etc - all of that works as expected
- action=QUEUES on source reflects the queueSize accurately. Also *always*
shows updateLogSynchronizer state as "stopped"
- action=LASTPROCESSEDVERSION on both source and target always seems correct (I
don't see the -1 that Sean mentioned).
- I'm creating new collections every time and running full data imports that
take 5-10 minutes. Again, all data replication, log rollover, and autocommit
activity seems to work as expected, and logs on target are deleted. It's just
those pesky source tlogs I can't get to delete.
