hi list, I am using Cassandra with 3 data centers, each DC has more than 10 nodes.
the schema for a keyspace: {DC1:3, DC2:3, DC3:3} now, I put some rows using hector with CL Local_Quorum in DC1 ,and then I get a row with the same CL Local_Quorum in DC1,some exceptions were occured: Cassandra with dsc-1.0.5, and Hector with 1.1-2. 2012-12-05 21:26:49,667 - WARN [pool-1-thread-3:JCLLoggerAdapter@379] - Could not fullfill request on this host CassandraClient172.16.74.31:9160-1 2012-12-05 21:26:49,668 - WARN [pool-1-thread-3:JCLLoggerAdapter@437] - Exception: me.prettyprint.hector.api.exceptions.HTimedOutException: TimedOutException() at me.prettyprint.cassandra.service.ExceptionsTranslatorImpl.translate(ExceptionsTranslatorImpl.java:35) at me.prettyprint.cassandra.service.KeyspaceServiceImpl$3.execute(KeyspaceServiceImpl.java:163) at me.prettyprint.cassandra.service.KeyspaceServiceImpl$3.execute(KeyspaceServiceImpl.java:145) at me.prettyprint.cassandra.service.Operation.executeAndSetResult(Operation.java:103) at me.prettyprint.cassandra.connection.HConnectionManager.operateWithFailover(HConnectionManager.java:258) at me.prettyprint.cassandra.service.KeyspaceServiceImpl.operateWithFailover(KeyspaceServiceImpl.java:131) at me.prettyprint.cassandra.service.KeyspaceServiceImpl.getRangeSlices(KeyspaceServiceImpl.java:167) at me.prettyprint.cassandra.model.thrift.ThriftRangeSlicesQuery$1.doInKeyspace(ThriftRangeSlicesQuery.java:66) at me.prettyprint.cassandra.model.thrift.ThriftRangeSlicesQuery$1.doInKeyspace(ThriftRangeSlicesQuery.java:62) at me.prettyprint.cassandra.model.KeyspaceOperationCallback.doInKeyspaceAndMeasure(KeyspaceOperationCallback.java:20) at me.prettyprint.cassandra.model.ExecutingKeyspace.doExecute(ExecutingKeyspace.java:85) at me.prettyprint.cassandra.model.thrift.ThriftRangeSlicesQuery.execute(ThriftRangeSlicesQuery.java:61) org.apache.thrift.server.TThreadPoolServer$WorkerProcess.run(TThreadPoolServer.java:176) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: TimedOutException() at org.apache.cassandra.thrift.Cassandra$get_range_slices_result.read(Cassandra.java:12830) at org.apache.cassandra.thrift.Cassandra$Client.recv_get_range_slices(Cassandra.java:762) at org.apache.cassandra.thrift.Cassandra$Client.get_range_slices(Cassandra.java:734) at me.prettyprint.cassandra.service.KeyspaceServiceImpl$3.execute(KeyspaceServiceImpl.java:151) ... 19 more any suggestion with this issue? thanks.
