Not an issue. It seems due to corruption in my side. |
Description of problem: My Cassandra is unable to perform maintenance. It may be a Cassandra bug. The error I see it: 17:43:01,355 ERROR [org.rhq.enterprise.server.operation.OperationServerServiceImpl] (http-/0.0.0.0:7080-73) The failed operation [rhq-resource-427988--1783761 045-1383586979530_=_rhq-resource-427988_=_1383586979598] had an error of: org.mc4j.ems.connection.EmsInvocationException: Exception on invocation of [takeSnap shot]javax.management.RuntimeMBeanException: java.lang.RuntimeException: Tried to create duplicate hard link to /data06/rhq/data/system/NodeIdInfo/snapshots/1 383586980828/system-NodeIdInfo-ic-1-Digest.sha1 ... Caused by: java.lang.RuntimeException: Tried to create duplicate hard link to /data06/rhq/data/system/NodeIdInfo/snapshots/1383586980828/system-NodeIdInfo-ic-1-Digest.sha1 at org.apache.cassandra.io.util.FileUtils.createHardLink(FileUtils.java:70) at org.apache.cassandra.io.sstable.SSTableReader.createLinks(SSTableReader.java:1081) at org.apache.cassandra.db.ColumnFamilyStore.snapshotWithoutFlush(ColumnFamilyStore.java:1567) at org.apache.cassandra.db.ColumnFamilyStore.snapshot(ColumnFamilyStore.java:1612) at org.apache.cassandra.db.Table.snapshot(Table.java:194) at org.apache.cassandra.service.StorageService.takeSnapshot(StorageService.java:2203) Version-Release number of selected component (if applicable): 4.9 How reproducible: Unclear. My installation may be corrupted in some way. Additional info: Clearing the existing snapshots doesn't seem to fix the issue. E.g.: ./nodetool -p 7299 clearsnapshot doesn't fix the problem, even on all 3 nodes.
