Mark Miller commented on SOLR-4236:
-----------------------------------
Hey Raintung, I have not had a chance to fully understand this yet, but is this
issue a dupe of SOLR-3933?
> Commit issue: Can't search while add commit=true in the call URL about insert
> index
> -----------------------------------------------------------------------------------
>
> Key: SOLR-4236
> URL: https://issues.apache.org/jira/browse/SOLR-4236
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.0-BETA, 4.0
> Environment: one collection, one shard, three sever, one leader, two
> duplicate
> Reporter: Raintung Li
> Labels: commit
>
> I setup three instances for solr cloud for one same collection and shards,
> the cloud is one instance is shard leader and the others are replicate.
> Send the index request to one instance, the URL example like this.
> curl "http://localhost:7002/solr/update?commit=true"; -H "Content-Type:
> text/xml" --data-binary '<add><doc><field name="id">test</field></doc></add>'
> If send the request to the leader server, only the leader server can search
> this index, the replicate can't search. I close the autoSoftCommit.
> If request send to the replicate server, all servers can't search this index.
> The major problem:
> SolrCmdDistributor
> distribAdd method will batch some requests in the cache.
> DistributedUpdateProcessor class method processCommit will trigger the send
> the distribute request after the send commit request.
> If send the testing index's request to replicate server, replicate server
> will dispatch the request to leader server. But in this case, commit command
> will send to the other server before actually index request. The index can be
> searched only wait the softCommit or the other commit command coming.
> A litter confuse: Why commit command don't need the leader server send to
> duplicate server? Only receive request server send the commit to full shards
> server?
> It look like solr doesn't implement the transaction logic.
