Hi
Using Solr trunk with the replica feature, I see the below exception
repeatedly in the Solr log.
I have been looking into the code of RecoveryStrategy#commitOnLeader and
read the code as follows:
1. sends a commit request (with COMMIT_END_POINT=true) to the Solr
instance containing the leader of the slice
2. sends a commit request to the Solr instance containing the leader of
the slice
The first results in a commit on the shards in the single leader Solr
instance and the second results in a commit on the shards in the single
leader Solr plus on all other Solrs having slices or replica belonging
to the collection.
I would expect that the first request is the relevant (and enough to do
a recovery of the specific replica).
Am I reading the second request wrong or is it a bug?
The code I'm referring to is
UpdateRequest ureq = new UpdateRequest();
ureq.setParams(new ModifiableSolrParams());
ureq.getParams().set(DistributedUpdateProcessor.COMMIT_END_POINT,
true);
ureq.getParams().set(RecoveryStrategy.class.getName(), baseUrl);
1. ureq.setAction(AbstractUpdateRequest.ACTION.COMMIT, false,
true).process(
server);
2. server.commit();
Thanks in advance for any input.
Best regards Trym R. Møller
