Hi, we have a 52 Cassandra nodes cluster running Apache Cassandra 1.2.13. As we are planning to migrate to Cassandra 2.0.10, we decide to do some tests and we noticed that once a node in the cluster have been upgraded to Cassandra 2.0.x, restarting a Cassandra 1.2.x will fail.
The tests were done on a 6 nodes cluster running Apache Cassandra 1.2.13 (x5) + Apache Cassandra 2.0.10 (x1) and using java 1.7.0_07. The cassandra 1.2.x is failing with the following error in output.log : INFO 15:18:41,233 Initializing system_traces.events org.apache.cassandra.db.marshal.MarshalException: unable to coerce 'credval' to a formatted date (long) at org.apache.cassandra.db.marshal.DateType.dateStringToTimestamp(DateType.java:115) at org.apache.cassandra.db.marshal.DateType.fromString(DateType.java:83) at org.apache.cassandra.db.marshal.ReversedType.fromString(ReversedType.java:82) at org.apache.cassandra.config.ColumnDefinition.fromSchema(ColumnDefinition.java:231) at org.apache.cassandra.config.CFMetaData.addColumnDefinitionSchema(CFMetaData.java:1524) at org.apache.cassandra.config.CFMetaData.fromSchema(CFMetaData.java:1456) at org.apache.cassandra.config.KSMetaData.deserializeColumnFamilies(KSMetaData.java:306) at org.apache.cassandra.config.KSMetaData.fromSchema(KSMetaData.java:287) at org.apache.cassandra.db.DefsTable.loadFromTable(DefsTable.java:154) at org.apache.cassandra.config.DatabaseDescriptor.loadSchemas(DatabaseDescriptor.java:583) at org.apache.cassandra.service.CassandraDaemon.setup(CassandraDaemon.java:253) at org.apache.cassandra.service.CassandraDaemon.init(CassandraDaemon.java:381) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.apache.commons.daemon.support.DaemonLoader.load(DaemonLoader.java:212) Caused by: java.text.ParseException: Unable to parse the date: credval at org.apache.commons.lang.time.DateUtils.parseDateWithLeniency(DateUtils.java:359) at org.apache.commons.lang.time.DateUtils.parseDateStrictly(DateUtils.java:305) at org.apache.cassandra.db.marshal.DateType.dateStringToTimestamp(DateType.java:111) ... 16 more Cannot load daemon Service exit with a return value of 3 We did some tests with a very simple schema without ReversedType, but they failed too. We did look at CASSANDRA-6695 and CASSANDRA-8462, and we had applied the corresponding patch, but without success. Does someone know a way to avoid this issue ? -- Close the World, Open the Net http://www.linux-wizard.net
