QUESTION

Apache Flink TaskExecutor shutting down

Asked 2019-Nov-25 at 13:11

I'm new to Apache Flink so I'm currently trying to do a few experiments. I'm reading a topic from Kafka and then printing it out on the console. After printing about 100k+ kafka messages, it throws exceptions. The log output is below.

I'm using a custom class which extends AbstractDeserializationSchema to deserialize the kafka record value. I've even tried putting some exception handling in that but that doesn't get triggered.

The code I use to consume from Kafka is pretty straightforward:

Change the JDK version to jdk-8u231-windows-x64. I had the same problem and eventually solved it by changing the version of the JDK.

Flink Temp Jar Upload Directory Deleted

Asked 2019-Feb-12 at 22:50

I have recently been unable to upload any jars to my Flink cluster, running under YARN on AWS EMR. There has been a long-running streaming application running for 26 days. It seems like the temp directory has been deleted, but I really don't think that I deleted it.

From the jobmanager.log:

ANSWER

Answered 2019-Feb-12 at 22:22

Some Linux distributions periodically clean up the temp directory (/tmp), i.e., not only on a restart.

You should configure Flink to use a non-temp directory to store the JARs.

The checkpoint you are referring to s3://bucket/kinesis-pipeline-checkpoint/a8a9ceb95845c3ea9833e025b5771470 does not contain a valid _metadata file. This indicates that this checkpoint was started but could not be completed. Please choose a checkpoint which has been successfully completed.

QUESTION

Max size of a fat JAR for Apache Flink

Asked 2018-Aug-23 at 11:25

I've build an Apache Flink app and packaged it in a fat JAR with Gradle Shadow Plugin. The resulting file size is ~114 MiB. When I'm trying to upload it with Flink's web UI it is stuck in "Saving…" phase. And if I use curl to upload it manually the result is "413 Request Entity Too Large":

...

ANSWER

Answered 2018-Aug-23 at 11:25

Ok, it was easy to fix.

First, I've scanned their repo for "Too Large" string and found this class. Looks like SERVER_MAX_CONTENT_LENGTH is responsible for max object size. It is set here from the configuration option rest.server.max-content-length. The default is 100 MiB.

TLDR:

Setting rest.server.max-content-length in flink-conf.yaml to 209715200 (200 MiB) solved the issue.

QUESTION

How to submit a job, by using an uploaded jar in Apache Flink?

Asked 2018-Jan-18 at 07:31

I've already uploaded a jar (which was generated through a word count java program) to Apache Flink web console through an HTTP Post request via curl and the get jars api shows the uploaded jar.

When I try to submit a job using that jar, it throws me this error:

Caused by: org.apache.flink.client.program.ProgramInvocationException: JAR file does not exist '/tmp/flink-web-8aa36f99-87fb-4fbc-b155-237fd833fc32/:949611ce-345a-4cd5-986b-8ff9b0700852_WordCount.jar'

This is how my POST request looks like:

Ensure that the jar file is located in your temp directory. There is a ':' in path, is it correct?
