I just upgraded from Cassandra 1.1.7 to 1.2.3 and im now seeing a lot of the following error in my output.log, cant find much on the web about it:
ERROR 11:56:01,317 Exception in thread Thread[ReadStage:7236,5,main] java.lang.AssertionError: Added column does not sort as the last column at org.apache.cassandra.db.ArrayBackedSortedColumns.addColumn(ArrayBackedSortedColumns.java:131) at org.apache.cassandra.db.AbstractColumnContainer.addColumn(AbstractColumnContainer.java:109) at org.apache.cassandra.db.AbstractColumnContainer.addColumn(AbstractColumnContainer.java:104) at org.apache.cassandra.db.filter.SliceQueryFilter.collectReducedColumns(SliceQueryFilter.java:171) at org.apache.cassandra.db.filter.QueryFilter.collateColumns(QueryFilter.java:136) at org.apache.cassandra.db.filter.QueryFilter.collateOnDiskAtom(QueryFilter.java:84) at org.apache.cassandra.db.CollationController.collectAllData(CollationController.java:294) at org.apache.cassandra.db.CollationController.getTopLevelColumns(CollationController.java:65) at org.apache.cassandra.db.ColumnFamilyStore.getTopLevelColumns(ColumnFamilyStore.java:1363) at org.apache.cassandra.db.ColumnFamilyStore.getColumnFamily(ColumnFamilyStore.java:1220) at org.apache.cassandra.db.ColumnFamilyStore.getColumnFamily(ColumnFamilyStore.java:1132) at org.apache.cassandra.db.Table.getRow(Table.java:348) at org.apache.cassandra.db.SliceFromReadCommand.getRow(SliceFromReadCommand.java:70) at org.apache.cassandra.service.StorageProxy$LocalReadRunnable.runMayThrow(StorageProxy.java:1052) at org.apache.cassandra.service.StorageProxy$DroppableRunnable.run(StorageProxy.java:1578) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662)
I dont know Java and im struggling to identify exactly which query is causing this, is there a way to trace this back to a specific query?
Any help appreciated.
