I had this type of exception when trying to build and test Flink on a "small machine". I worked around the test increasing the timeout for Akka.

Is it possible that on load situations the JobManager slows down a bit too much? saluti, Stefano 2016-04-27 17:50 GMT+02:00 Flavio Pompermaier <pomperma...@okkam.it>: > A precursor of the modified connector (since we started a long time ago). > However the idea is the same, I compute the inputSplits and then I get the > data split by split (similarly to what it happens in FLINK-3750 - > https://github.com/apache/flink/pull/1941 ) > > Best, > Flavio > > On Wed, Apr 27, 2016 at 5:38 PM, Chesnay Schepler <ches...@apache.org> > wrote: > >> Are you using your modified connector or the currently available one? >> >> >> On 27.04.2016 17:35, Flavio Pompermaier wrote: >> >> Hi to all, >> I'm running a Flink Job on a JDBC datasource and I obtain the following >> exception: >> >> java.lang.RuntimeException: Requesting the next InputSplit failed. >> at >> org.apache.flink.runtime.taskmanager.TaskInputSplitProvider.getNextInputSplit(TaskInputSplitProvider.java:91) >> at >> org.apache.flink.runtime.operators.DataSourceTask$1.hasNext(DataSourceTask.java:342) >> at >> org.apache.flink.runtime.operators.DataSourceTask.invoke(DataSourceTask.java:137) >> at org.apache.flink.runtime.taskmanager.Task.run(Task.java:559) >> at java.lang.Thread.run(Thread.java:745) >> Caused by: java.util.concurrent.TimeoutException: Futures timed out after >> [10000 milliseconds] >> at scala.concurrent.impl.Promise$DefaultPromise.ready(Promise.scala:219) >> at scala.concurrent.impl.Promise$DefaultPromise.result(Promise.scala:223) >> at scala.concurrent.Await$$anonfun$result$1.apply(package.scala:107) >> at >> scala.concurrent.BlockContext$DefaultBlockContext$.blockOn(BlockContext.scala:53) >> at scala.concurrent.Await$.result(package.scala:107) >> at scala.concurrent.Await.result(package.scala) >> at >> org.apache.flink.runtime.taskmanager.TaskInputSplitProvider.getNextInputSplit(TaskInputSplitProvider.java:71) >> ... 4 more >> >> What can be the cause?
