in our test,we used solrcloud feature in solr4.0(version detail :184.108.40.2062.10.06.03.04.33).
the solrcloud configuration is 3 shards and 2 replications each shard.
we found that there are over than 25 dirs which named index.
in one replication node belonging to shard 3.
index.20130217233335864 index.20130218012211880 index.20130218015714713 index.20130218023101958 index.20130218030424083 tlog
index.20130218005648324 index.20130218012751078 index.20130218020141293
the issue seems like
SOLR-1781. but it is fixed in 4.0-BETA,5.0.
so is solr4.0 ? if it is fixed too in solr4.0, why we find the issue again ?
what can I do?
