Spark Streaming Fails on Cluster mode ( Flume as source)

tarekabouzeid91 — Fri, 16 Sep 2022 09:24:09 GMT

i am using spark streaming , event count example , flume as source of avro events , everything works fine when executing spark on local mode , but when i try to run the example on my cluster i got failed to bind error ,

Command line thats working " local mode "

spark-submit --class "WordCount" --master local[*] --jars /opt/cloudera/parcels/CDH-5.3.1-1.cdh5.3.1.p0.5/lib/spark/lib/spark-streaming-flume_2.10-1.2.0.jar,/opt/cloudera/parcels/CDH-5.3.1-1.cdh5.3.1.p0.5/lib/flume-ng/lib/avro-ipc.jar,/opt/cloudera/parcels/CDH-5.3.1-1.cdh5.3.1.p0.5/lib/flume-ng/lib/flume-ng-sdk-1.5.0-cdh5.3.1.jar /usr/local/WordCount/target/scala-2.10/wordcount_2.10-1.0.jar node01 6789

Command line that's not working " cluster mode "

spark-submit --class "WordCount" --master spark://node01:7077 --jars /opt/cloudera/parcels/CDH-5.3.1-1.cdh5.3.1.p0.5/lib/spark/lib/spark-streaming-flume_2.10-1.2.0.jar,/opt/cloudera/parcels/CDH-5.3.1-1.cdh5.3.1.p0.5/lib/flume-ng/lib/avro-ipc.jar,/opt/cloudera/parcels/CDH-5.3.1-1.cdh5.3.1.p0.5/lib/flume-ng/lib/flume-ng-sdk-1.5.0-cdh5.3.1.jar /usr/local/WordCount/target/scala-2.10/wordcount_2.10-1.0.jar node01 6789

As you can see, the problem is that the receiver can't bind to its assigned address. Is there any networking-related restriction in place that would prevent this? is this the port you intended?

i guess there's no network restrictions , all 3 nodes that i am using are configured to work together normally , but i read that when spark deploy the code on a worker it starts to listen to the port , while another worker is already using listening on this port so it cause the faliure , check this http://apache-spark-user-list.1001560.n3.nabble.com/How-to-use-FlumeInputDStream-in-spark-cluster-td1604.html

but if there's a network problem , what might it be ? i have 3 nodes 1 master and 2 workers , i can submit any job using master and it appears working on the 2 workers ,, but the network word count isn't working on cluster mode , so lets assume its a network problem , what might it be ?

Although that thread sounds similar, I don't think it's the same thing. Failing to bind is not a failure to connect to a remote host. It means the local host didn't allow the process to listen on a port. The two most likely explanations are:

- an old process is still listening on that port, or at least, another still-running process is

- you appear to be binding to a non-routable address (192.168.x.x) This might be OK but worth double-checking

i fixed that problem by making the spark listen to node02 and flume send events to node02 , that fixed the problem acutally , thanks so much for your help

Hi sowen

We actually have the same problem of filed to bind with the internal ip-port 10.1.0.11:50321.

The question is that sometimes connect Spark Streaming with the port and sometimes didn´t it and when the did not connect sometimes in 5 -7 min that Spark Streaming is trying connect.

Do you know what is the possible cause?

We install Spark 1.5.1 on clouderas 5.3.7 (with YARN).

Best regards
