Re: Apache Flink 1.0.3 IllegalStateException Partiction State on chaining

2016-07-13 Thread ANDREA SPINA 
Hi everybody,
increasing the akka.ask.timeout solved the second issue. Anyway that was a
warning about a congestioned network. So I worked to improve the algorithm.
Increasing the numberOfBuffers and the corresponding size solved the first
issue, thus now I can run with the full DOP.
In my case enabling the off-heap memory didn't the trick.

Thank you. All the bests,
Andrea

Re: Apache Flink 1.0.3 IllegalStateException Partiction State on chaining

2016-06-29 Thread Martin Scholl 
Other than increasing the ask.timeout, we've seen such failures being
caused by long GC pauses over bigger heaps. In such a case, you could
fiddle with a) enabling object reuse, or b) enabling off-heap memory (i.e.
taskmanager.memory.off-heap == true) to mitigate GC-induced issues a bit.

Hope it helps,
Martin

Re: Apache Flink 1.0.3 IllegalStateException Partiction State on chaining

2016-06-29 Thread Ufuk Celebi 
OK, looks like you can easily give more memory to the network stack,
e.g. for 2 GB set

taskmanager.network.numberOfBuffers = 65536
taskmanager.network.bufferSizeInBytes = 32768

For the other exception, your logs confirm that there is something
else going on. Try increasing the akka ask timeout:

akka.ask.timeout: 100 s

Does this help?

Hi Ufuk,

so the memory available per node is 48294 megabytes per node, but I reserve
28 by flink conf file.
taskmanager.heap.mb = 28672
taskmanager.memory.fraction = 0.7
taskmanager.network.numberOfBuffers = 32768
taskmanager.network.bufferSizeInBytes = 16384

Anyway Follows what I found in log files.

Re: Apache Flink 1.0.3 IllegalStateException Partiction State on chaining

2016-06-29 Thread Ufuk Celebi 
Hey Andrea! Sorry for the bad user experience.

Regarding the network buffers: you should be able to run it after
increasing the number of network buffers, just account for it when
specifying the heap size etc. You currently allocate 32768 * 16384
bytes = 512 MB for them. If you have a very long pipeline and high
parallelism, you should increase it accordingly. How much memory do
you have on your machines?

Regarding the IllegalStateException: I suspect that this is **not**
the root failure cause. The null ExecutionState can only happen, if
the producer task (from which data is requested) failed during the
request. The error message is confusing and I opened a JIRA to fix it:
https://issues.apache.org/jira/browse/FLINK-4131. Can you please check
your complete logs to see what the root cause might be, e.g. why did
the producer fail?

Apache Flink 1.0.3 IllegalStateException Partiction State on chaining

2016-06-29 Thread ANDREA SPINA 
Hi everyone,

I am running some Flink experiments with Peel benchmark
http://peel-framework.org/ and I am struggling with exceptions: the
environment is a 25-nodes cluster, 16 cores per nodes. The dataset is
~80GiB and is located on Hdfs 2.7.1. Flink version is 1.0.3.

At the beginning I tried with 400 as degree of parallelism but not enough
numberOfBuffers was raised so I changed the parallelism to 200. Flink
configuration follows:

jobmanager.rpc.address = ${runtime.hostname}
akka.log.lifecycle.events = ON
akka.ask.timeout = 300s
jobmanager.rpc.port = 6002
jobmanager.heap.mb = 1024
jobmanager.web.port = 6004
taskmanager.heap.mb = 28672
taskmanager.memory.fraction = 0.7
taskmanager.network.numberOfBuffers = 32768
taskmanager.network.bufferSizeInBytes = 16384
taskmanager.tmp.dirs =
"/data/1/peel/flink/tmp:/data/2/peel/flink/tmp:/data/3/peel/flink/tmp:/data/4/peel/flink/tmp"
taskmanager.debug.memory.startLogThread = true

With a parallelism of 200 the following exception will raise from a node of
the cluster:

2016-06-29 11:31:55,673 INFO  org.apache.flink.runtime.taskmanager.Task
- CHAIN Reduce (Reduce at dima.tu.berlin.benchmark.fli
nk.mlr.solver.sGradientDescentL2.createInitialWeightsVector(sGradientDescentL2.scala:43))
-> Map (Map at dima.tu.berlin.benchmark.flink.mlr.solver
.sGradientDescentL2.createInitialVector(sGradientDescentL2.scala:69)) (1/1)
switched to FAILED with exception.
java.lang.IllegalStateException: Received unexpected partition state null
for partition request. This is a bug.
at
org.apache.flink.runtime.taskmanager.Task.onPartitionStateUpdate(Task.java:994)


The reduce code is:

43  val dimensionsDS = data.map(_.vector.size).reduce((a, b) => b)

The map code is:

68  def createInitialVector(dimensionDS: DataSet[Int]): DataSet[Vector] = {
69dimensionDS.map {
70  dimension =>
71  val values = DenseVector(Array.fill(dimension)(0.0))
72  values
73}
74  }

I can't figure out a solution, thank you for your help.

Andrea
