Hello, I have recently installed Datastax-Cassandra-2.2.0 on a Debian system. I successfully started Cassandra.
In order to test it, I have written a small client in Java that use cassandra-driver-core-2.1.7.1.jar from Datastax. I also installed the DevCenter in order to create a keyspace and a table. Here is the generated CQL CREATE KEYSPACE IF NOT EXISTS test WITH REPLICATION = { 'class' : 'NetworkTopologyStrategy', 'datacenter1' : 3 }; CREATE TABLE IF NOT EXISTS test.incoming_message ( id uuid, device_id text, creation_date date, event_timestamp timestamp, raw_message text, PRIMARY KEY ((device_id, creation_date ), event_timestamp) ) WITH CLUSTERING ORDER BY (event_timestamp DESC); Based on this http://cassandra.apache.org/doc/cql3/CQL-2.2.html#usingdates, I used 'date' type to define a column 'creation_date' for 'incoming_message' table I tried to insert data in the table with this code: Insert insert = QueryBuilder.insertInto("incoming_message") .value("id", UUIDs.random()) .value("device_id", celloMessage.getUnitID()) .value("creation_date", SimpleDateSerializer.timeInMillisToDay(DateTime.now(DateTimeZone.UTC).getMillis())) .value("event_timestamp", DateTime.now(DateTimeZone.UTC).getMillis()) .value("raw_message", Hex.encodeHexString(celloMessage.getMessage())); I use a helper class SimpleDateSerializer in order to format the date. This class can be found in Cassandra-clientutil-2.2.0.jar When I try to insert records, I have this stack: Caused by: com.datastax.driver.core.exceptions.InvalidQueryException: Unable to make unsigned int (for date) from: '-2147466980' at com.datastax.driver.core.Responses$Error.asException(Responses.java:102) at com.datastax.driver.core.DefaultResultSetFuture.onSet(DefaultResultSetFuture.java:118) at com.datastax.driver.core.RequestHandler.setFinalResult(RequestHandler.java:183) at com.datastax.driver.core.RequestHandler.access$2300(RequestHandler.java:45) at com.datastax.driver.core.RequestHandler$SpeculativeExecution.setFinalResult(RequestHandler.java:748) at com.datastax.driver.core.RequestHandler$SpeculativeExecution.onSet(RequestHandler.java:573) at com.datastax.driver.core.Connection$Dispatcher.channelRead0(Connection.java:991) at com.datastax.driver.core.Connection$Dispatcher.channelRead0(Connection.java:913) at io.netty.channel.SimpleChannelInboundHandler.channelRead(SimpleChannelInboundHandler.java:105) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:308) at io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:294) at io.netty.handler.timeout.IdleStateHandler.channelRead(IdleStateHandler.java:254) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:308) at io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:294) at io.netty.handler.codec.MessageToMessageDecoder.channelRead(MessageToMessageDecoder.java:103) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:308) at io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:294) at io.netty.handler.codec.ByteToMessageDecoder.channelRead(ByteToMessageDecoder.java:244) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:308) at io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:294) at io.netty.channel.DefaultChannelPipeline.fireChannelRead(DefaultChannelPipeline.java:846) at io.netty.channel.nio.AbstractNioByteChannel$NioByteUnsafe.read(AbstractNioByteChannel.java:131) at io.netty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:511) at io.netty.channel.nio.NioEventLoop.processSelectedKeysOptimized(NioEventLoop.java:468) at io.netty.channel.nio.NioEventLoop.processSelectedKeys(NioEventLoop.java:382) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:354) ... 2 more What Am I doing wrong? Thank you for your help. Regards Philippe SURAY
