Re: Unable to run the batch examples after running stream examples

the project.version property is not defined explicitly; it resembles the version of the parent.

Plan#getRestartStrategyConfiguration() exists in Flink 1.0.0, but not in 1.1-SNAPSHOT.

When you set the version to 1.0.0 you may have created this version mismatch.

Hello Chesnay Schepler, 

I am running the latest flink examples from here in eclipse.
I had used the WikipediaAnalysis pom properties/dependency in batch pom as shown below:

            <properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<flink.version>1.0.0</flink.version>

          </properties>

          <dependency>

<groupId>org.apache.flink</groupId>

<artifactId>flink-java</artifactId>

<version>1.0.0</version>

</dependency>

<dependency>

<groupId>org.apache.flink</groupId>

<artifactId>flink-streaming-java_2.10</artifactId>

<version>${flink.version}</version>

</dependency>

But the original pom of batch has dependency:

                <dependency>

<groupId>org.apache.flink</groupId>

<artifactId>flink-java</artifactId>

<version>${project.version}</version>

</dependency>

Shouldn't both the above mean the same? I couldn't find the pom file where 'project.version' property was defined. Yeah it's working when I used the original pom of batch, but I am confused why the modified one is not working.

where did you run the batch/streaming jobs? did both job use the same flink version?

Hello all,

The scenario is I am working on Kafka Read/Write examples. It works fine, but now when I try to run the batch examples such as PiEstimation or any other, I get the following error:

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.flink.api.common.Plan.getRestartStrategyConfiguration()Lorg/apache/flink/api/common/restartstrategy/RestartStrategies$RestartStrategyConfiguration;

Previously before running the Kafka examples, the batch examples were working fine, now not. Now only the streaming examples are working.
