My bad. Moved to Cassandra user list. -----Original Message----- From: Aditya Muralidharan [mailto:aditya.muralidha...@nisc.coop] Sent: Wednesday, November 10, 2010 10:48 AM To: u...@pig.apache.org Subject: RE: MapReduce/Hadoop in cassandra 0.7 beta3
Hi, I'm still getting the error associated with https://issues.apache.org/jira/browse/CASSANDRA-1700 I have 7 suse nodes running Cassandra0.7 branch (latest as of the morning of Nov 9). I've loaded 10 rows with one column family(replication factor=4) and 100 super columns. Using the ColumnFamilyInputFormat with mapreduce (LocalJobRunner) to retrieve all the rows gives me the following exception: 10/11/10 10:33:15 WARN mapred.LocalJobRunner: job_local_0001 java.lang.RuntimeException: org.apache.thrift.TApplicationException: Internal error processing get_range_slices at org.apache.cassandra.hadoop.ColumnFamilyRecordReader$RowIterator.maybeInit(ColumnFamilyRecordReader.java:277) at org.apache.cassandra.hadoop.ColumnFamilyRecordReader$RowIterator.computeNext(ColumnFamilyRecordReader.java:292) at org.apache.cassandra.hadoop.ColumnFamilyRecordReader$RowIterator.computeNext(ColumnFamilyRecordReader.java:189) at com.google.common.collect.AbstractIterator.tryToComputeNext(AbstractIterator.java:136) at com.google.common.collect.AbstractIterator.hasNext(AbstractIterator.java:131) at org.apache.cassandra.hadoop.ColumnFamilyRecordReader.nextKeyValue(ColumnFamilyRecordReader.java:148) at org.apache.hadoop.mapred.MapTask$NewTrackingRecordReader.nextKeyValue(MapTask.java:423) at org.apache.hadoop.mapreduce.MapContext.nextKeyValue(MapContext.java:67) at org.apache.hadoop.mapreduce.Mapper.run(Mapper.java:143) at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:621) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:305) at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:177) Caused by: org.apache.thrift.TApplicationException: Internal error processing get_range_slices at org.apache.thrift.TApplicationException.read(TApplicationException.java:108) at org.apache.cassandra.thrift.Cassandra$Client.recv_get_range_slices(Cassandra.java:724) at org.apache.cassandra.thrift.Cassandra$Client.get_range_slices(Cassandra.java:704) at org.apache.cassandra.hadoop.ColumnFamilyRecordReader$RowIterator.maybeInit(ColumnFamilyRecordReader.java:255) ... 11 more The server has the following exception: ERROR [pool-1-thread-11] 2010-11-10 10:35:58,839 Cassandra.java (line 2876) Internal error processing get_range_slices java.lang.AssertionError: (150596448267070854052355226693835429313,18886431880788352792108545029372560769] at org.apache.cassandra.db.ColumnFamilyStore.getRangeSlice(ColumnFamilyStore.java:1200) at org.apache.cassandra.service.StorageProxy.getRangeSlice(StorageProxy.java:429) at org.apache.cassandra.thrift.CassandraServer.get_range_slices(CassandraServer.java:513) at org.apache.cassandra.thrift.Cassandra$Processor$get_range_slices.process(Cassandra.java:2868) at org.apache.cassandra.thrift.Cassandra$Processor.process(Cassandra.java:2555) at org.apache.cassandra.thrift.CustomTThreadPoolServer$WorkerProcess.run(CustomTThreadPoolServer.java:167) 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:619) Any help would be appreciated.
