Hi, guys: I have an online application with solrcloud 4.1, but I get errors of syncpeer every 2 or 3 weeks... In my opinion, a recover occers when a replica can not sync data to its leader successfully.
I see the topic http://lucene.472066.n3.nabble.com/SolrCloud-5x-Errors-while-recovering-td4022542.html and https://issues.apache.org/jira/i#browse/SOLR-4032, but why did I still get similar errors in solrcloud4.1? so is there any settings for syncpeer? how to reduce the probability of this error? when recover happens, how to ensure its success? The errors I got is like these: [2013.10.21 10:39:13.482]2013-10-21 10:39:13,482 WARN [org.apache.solr.handler.SnapPuller] - Error in fetching packets [2013.10.21 10:39:13.482]java.io.EOFException [2013.10.21 10:39:13.482] at org.apache.solr.common.util.FastInputStream.readFully(FastInputStream.java:154) [2013.10.21 10:39:13.482] at org.apache.solr.common.util.FastInputStream.readFully(FastInputStream.java:146) [2013.10.21 10:39:13.482] at org.apache.solr.handler.SnapPuller$DirectoryFileFetcher.fetchPackets(SnapPuller.java:1136) [2013.10.21 10:39:13.482] at org.apache.solr.handler.SnapPuller$DirectoryFileFetcher.fetchFile(SnapPuller.java:1099) [2013.10.21 10:39:13.482] at org.apache.solr.handler.SnapPuller.downloadIndexFiles(SnapPuller.java:738) [2013.10.21 10:39:13.482] at org.apache.solr.handler.SnapPuller.fetchLatestIndex(SnapPuller.java:395) [2013.10.21 10:39:13.482] at org.apache.solr.handler.ReplicationHandler.doFetch(ReplicationHandler.java:274) [2013.10.21 10:39:13.482] at org.apache.solr.cloud.RecoveryStrategy.replicate(RecoveryStrategy.java:153) [2013.10.21 10:39:13.482] at org.apache.solr.cloud.RecoveryStrategy.doRecovery(RecoveryStrategy.java:409) [2013.10.21 10:39:13.482] at org.apache.solr.cloud.RecoveryStrategy.run(RecoveryStrategy.java:223) [2013.10.21 10:39:13.485]2013-10-21 10:39:13,485 WARN [org.apache.solr.handler.SnapPuller] - Error in fetching packets [2013.10.21 10:39:13.485]java.io.EOFException [2013.10.21 10:39:13.485] at org.apache.solr.common.util.FastInputStream.readFully(FastInputStream.java:154) [2013.10.21 10:39:13.485] at org.apache.solr.common.util.FastInputStream.readFully(FastInputStream.java:146) [2013.10.21 10:39:13.485] at org.apache.solr.handler.SnapPuller$DirectoryFileFetcher.fetchPackets(SnapPuller.java:1136) [2013.10.21 10:39:13.485] at org.apache.solr.handler.SnapPuller$DirectoryFileFetcher.fetchFile(SnapPuller.java:1099) [2013.10.21 10:39:13.485] at org.apache.solr.handler.SnapPuller.downloadIndexFiles(SnapPuller.java:738) [2013.10.21 10:39:13.485] at org.apache.solr.handler.SnapPuller.fetchLatestIndex(SnapPuller.java:395) [2013.10.21 10:39:13.485] at org.apache.solr.handler.ReplicationHandler.doFetch(ReplicationHandler.java:274) [2013.10.21 10:39:13.485] at org.apache.solr.cloud.RecoveryStrategy.replicate(RecoveryStrategy.java:153) [2013.10.21 10:39:13.485] at org.apache.solr.cloud.RecoveryStrategy.doRecovery(RecoveryStrategy.java:409) [2013.10.21 10:39:13.485] at org.apache.solr.cloud.RecoveryStrategy.run(RecoveryStrategy.java:223) [2013.10.21 10:41:08.461]2013-10-21 10:41:08,461 ERROR [org.apache.solr.handler.ReplicationHandler] - SnapPull failed :org.apache.solr.common.SolrException: Unable to download _fi05_Lucene41_0.pos completely.
