Hi, I see some data stored in Cassandra (2.0.7) being not readable from CQL; this affects entire partitions, querying this partitions raise a Java exception:
ERROR [ReadStage:540638] 2014-09-28 12:40:38,992 CassandraDaemon.java (line 198) Exception in thread Thread[ReadStage:540638,5,main] java.lang.RuntimeException: java.lang.IllegalArgumentException at org.apache.cassandra.service.StorageProxy$DroppableRunnable.run(StorageProxy.java:1920) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744) Caused by: java.lang.IllegalArgumentException at java.nio.Buffer.limit(Buffer.java:267) at org.apache.cassandra.db.marshal.AbstractCompositeType.getBytes(AbstractCompositeType.java:63) at org.apache.cassandra.db.marshal.AbstractCompositeType.getWithShortLength(AbstractCompositeType.java:72) at org.apache.cassandra.db.marshal.AbstractCompositeType.split(AbstractCompositeType.java:138) at org.apache.cassandra.db.filter.ColumnCounter$GroupByPrefix.count(ColumnCounter.java:116) at org.apache.cassandra.db.filter.SliceQueryFilter.collectReducedColumns(SliceQueryFilter.java:192) at org.apache.cassandra.db.filter.QueryFilter.collateColumns(QueryFilter.java:122) at org.apache.cassandra.db.filter.QueryFilter.collateOnDiskAtom(QueryFilter.java:80) at org.apache.cassandra.db.filter.QueryFilter.collateOnDiskAtom(QueryFilter.java:72) at org.apache.cassandra.db.CollationController.collectAllData(CollationController.java:297) at org.apache.cassandra.db.CollationController.getTopLevelColumns(CollationController.java:53) at org.apache.cassandra.db.ColumnFamilyStore.getTopLevelColumns(ColumnFamilyStore.java:1540) at org.apache.cassandra.db.ColumnFamilyStore.getColumnFamily(ColumnFamilyStore.java:1369) at org.apache.cassandra.db.Keyspace.getRow(Keyspace.java:327) at org.apache.cassandra.db.SliceFromReadCommand.getRow(SliceFromReadCommand.java:65) at org.apache.cassandra.service.StorageProxy$LocalReadRunnable.runMayThrow(StorageProxy.java:1352) at org.apache.cassandra.service.StorageProxy$DroppableRunnable.run(StorageProxy.java:1916) ... 5 more I tried to dump the sshtable to json but that was not really helpful; the table has bunch of cols and one composite map column, and the data is stored using python driver. Anyone has a suggestion on how to get more on this issue? Tommaso
