Benjamin Lerer commented on CASSANDRA-9906: ------------------------------------------- I will have another look at the patch as this change is probably wrong. The original {{ColumnFilter}} was not working properly and the thrift call was not returning anything. I changed it to make it work but I did not realize that I was returning more data than expected. > get_slice and multiget_slice failing on trunk > --------------------------------------------- > > Key: CASSANDRA-9906 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9906 > Project: Cassandra > Issue Type: Bug > Components: Core > Reporter: Mike Adamson > Assignee: Benjamin Lerer > Priority: Blocker > Fix For: 3.0.0 rc1 > > Attachments: 9906.txt, dtest-CASSANDRA-9906.txt > > > {{get_slice}} and {{multiget_slice}} are failing on trunk with the following > error: > {noformat} > java.lang.AssertionError: null > at > org.apache.cassandra.db.filter.ClusteringIndexNamesFilter.<init>(ClusteringIndexNamesFilter.java:53) > ~[cassandra-all-3.0.0.592.jar:3.0.0.592] > at > org.apache.cassandra.thrift.CassandraServer.toInternalFilter(CassandraServer.java:405) > ~[cassandra-all-3.0.0.592.jar:5.0.0-SNAPSHOT] > at > org.apache.cassandra.thrift.CassandraServer.multigetSliceInternal(CassandraServer.java:547) > ~[cassandra-all-3.0.0.592.jar:5.0.0-SNAPSHOT] > at > org.apache.cassandra.thrift.CassandraServer.multiget_slice(CassandraServer.java:348) > ~[cassandra-all-3.0.0.592.jar:5.0.0-SNAPSHOT] > at > org.apache.cassandra.thrift.Cassandra$Processor$multiget_slice.getResult(Cassandra.java:3716) > ~[cassandra-thrift-3.0.0.592.jar:5.0.0-SNAPSHOT] > at > org.apache.cassandra.thrift.Cassandra$Processor$multiget_slice.getResult(Cassandra.java:3700) > ~[cassandra-thrift-3.0.0.592.jar:5.0.0-SNAPSHOT] > at org.apache.thrift.ProcessFunction.process(ProcessFunction.java:39) > ~[libthrift-0.9.2.jar:0.9.2] > at org.apache.thrift.TBaseProcessor.process(TBaseProcessor.java:39) > ~[libthrift-0.9.2.jar:0.9.2] > at > org.apache.cassandra.thrift.CustomTThreadPoolServer$WorkerProcess.run(CustomTThreadPoolServer.java:204) > ~[cassandra-all-3.0.0.592.jar:5.0.0-SNAPSHOT] > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) > ~[na:1.8.0_45] > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) > ~[na:1.8.0_45] > at java.lang.Thread.run(Thread.java:745) ~[na:1.8.0_45] > {noformat} > The schema used for this was > {noformat} > create table test (k int, v int, primary key(k)) with compact storage; > {noformat} > and the code used for the call was > {noformat} > SlicePredicate predicate = new SlicePredicate(); > predicate.column_names = > Collections.singletonList(ByteBufferUtil.bytes("v")); > client.multiget_slice(Collections.singletonList(key), new > ColumnParent("test"), predicate, ConsistencyLevel.ONE); > {noformat} > The error is coming from this line in {{ClusteringIndexNamesFilter}} > {noformat} > assert !clusterings.contains(Clustering.STATIC_CLUSTERING); > {noformat} > which is failing the assertion because column 'v' is static. > Apologies for the line mismatches in {{ClusteringIndexNamesFilter}} I had > some debug statements in the code to help track down what was happening -- This message was sent by Atlassian JIRA (v6.3.4#6332)
