HuangTongwen commented on SOLR-6138: ------------------------------------ Thank you for your replys.I know that it is zookeeper's znode limit.But I tickout the 1MB limit.Then it happened like that.Sometime I create core with the parameter onStartup that I can enlarge cores more than 4000+ cores.Even if I use it than I increase cores.But I don't the loggers in solr board why I reload would happened to some errors,I think that it isn't znode limit.Any other error? > Solr core load limit > -------------------- > > Key: SOLR-6138 > URL: https://issues.apache.org/jira/browse/SOLR-6138 > Project: Solr > Issue Type: Bug > Components: clients - java > Affects Versions: 4.6, 4.7.1 > Environment: ubuntu 12.04 > memery 20G > Reporter: HuangTongwen > Labels: test > Original Estimate: 840h > Remaining Estimate: 840h > > We want to enrich our search ability by solr.We do an exercise for test that > how many cores in one machine solr cores can support. > We find we can create more than 2000 cores without datas in one machine.But > when we create cores with data ,we just can create about 1000 cores,after > more t han 1000 cores,we meet many errors like following I will apend it .If > you have meets the same or similar problem,please tell me. > I would be grateful if you could help me. > Hear are some errors: > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:43:29 WARN SolrResourceLoader Can't find (or read) directory > to add to classloader: /non/existent/dir/yields/warning (resolved as: > /non/existent/dir/yields/warning). > 09:46:15 ERROR ShardLeaderElectionContext There was a problem > trying to register as the > leader:org.apache.zookeeper.KeeperException$NodeExistsException: > KeeperErrorCode = NodeExists for /collections/ctest.test.3521/leaders/shard1 > 09:46:15 WARN ElectionContext cancelElection did not find > election node to remove > 09:46:16 WARN RecoveryStrategy Stopping recovery for > zkNodeName=core_node1core=ctest.test.3521 > 09:46:17 ERROR RecoveryStrategy Error while trying to recover. > core=ctest.test.3521:org.apache.solr.common.SolrException: No registered > leader was found, collection:ctest.test.3521 slice:shard1 > 09:46:17 ERROR RecoveryStrategy Recovery failed - trying > again...
