Hi There,

I'm using the cassandra-unloader to export the data from table but i'm getting timeout and i didn't find any options to increase the timeout.

./cassandra-unloader -f stdout -host xxxxxxx -schema "xxx.xxxx(xxx,bool,xxx,xxx,xxx,create_ts,create_user_urn,date,description,last_check_ts,last_update_ts,xxx,name,num,xx,xxxrsion,state,str,text_search,time_to_live,xxx)" -where "solr_query='xxxxx:XXXX' LIMIT 100000" > xxxx.xxxx.csv Exception in thread "main" java.util.concurrent.ExecutionException: com.datastax.driver.core.exceptions.OperationTimedOutException: [/10.XX.XX.XX:9042] Timed out waiting for server response at java.util.concurrent.FutureTask.report(FutureTask.java:122) at java.util.concurrent.FutureTask.get(FutureTask.java:192) at com.datastax.loader.CqlDelimUnload.run(CqlDelimUnload.java:402) at com.datastax.loader.CqlDelimUnload.main(CqlDelimUnload.java:471) Caused by: com.datastax.driver.core.exceptions.OperationTimedOutException: [/10.XX.XX.XX:9042] Timed out waiting for server response at com.datastax.driver.core.exceptions.OperationTimedOutException.copy(OperationTimedOutException.java:44) at com.datastax.driver.core.exceptions.OperationTimedOutException.copy(OperationTimedOutException.java:26) at com.datastax.driver.core.DriverThrowables.propagateCause(DriverThrowables.java:37) at com.datastax.driver.core.DefaultResultSetFuture.getUninterruptibly(DefaultResultSetFuture.java:245) at com.datastax.driver.core.AbstractSession.execute(AbstractSession.java:68) at com.datastax.loader.CqlDelimUnload$ThreadExecute.execute(CqlDelimUnload.java:599) at com.datastax.loader.CqlDelimUnload$ThreadExecute.call(CqlDelimUnload.java:534) at com.datastax.loader.CqlDelimUnload$ThreadExecute.call(CqlDelimUnload.java:479) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: com.datastax.driver.core.exceptions.OperationTimedOutException: [/10.XX.XX.XX:9042] Timed out waiting for server response at com.datastax.driver.core.RequestHandler$SpeculativeExecution.onTimeout(RequestHandler.java:772) at com.datastax.driver.core.Connection$ResponseHandler$1.run(Connection.java:1380) at io.netty.util.HashedWheelTimer$HashedWheelTimeout.expire(HashedWheelTimer.java:625) at io.netty.util.HashedWheelTimer$HashedWheelBucket.expireTimeouts(HashedWheelTimer.java:700) at io.netty.util.HashedWheelTimer$Worker.run(HashedWheelTimer.java:428) at io.netty.util.concurrent.DefaultThreadFactory$DefaultRunnableDecorator.run(DefaultThreadFactory.java:144) ... 1 more

Have you tried setting -queryTimeout?

[mdtx001]

I don't see -queryTimeout as a valid option for cassandra-unloader. (version: 0.0.27). I get the help screen when I try to add it to my command line options. We are having issues running the tool successfully after upgrading from Cassandra 2.0.9 to Cassandra 2.1.14. Heap is set to 8G, but the error is java.lang.OutOfMemoryError: Java heap space

Just type cassandra-loader and you will see the list of options, there will be queryTimeout.

Use it as cassandra-loader ... -queryTimeout 120

that works for cassandra-loader, it may work in your case.

Regards,

Xavier

-queryTimeout is not a valid option of cassandra-unloader. Did anyone find the solution?

Thanks!
