Re: Getting NoMethod found error while running job on flink 1.6.1


Flink is running as standalone cluster in High Availability mode, My application jar is a fat jar which has all the necessary dependencies included. 

I will check once again and verify by adding the flink-metrics-core to the classpath.

Thanks

Hi Chandu,

What mode does your Flink run in? 
In addition, can you check if the flink-metrics-core is included in the classpath of the Flink runtime environment?

Thanks, vino.

Hello,

I am have a job that reads messages from kafka, processes them and writes back to kafka, this jobs works fine on flink 1.3.2. I upgraded cluster to 1.6.1 but now see below error. Has any one faced similar issue?

I have updated all the dependencies to use 
<flink.version>1.6.1</flink.version>
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-connector-kafka-0.10_${scala.version}</artifactId>
<version>${flink.version}</version>
</dependency>
