Rick Kellogg commented on STORM-679:
------------------------------------
Should be as easy as changing the single maven-compiler-plugin setting in the
root pom.xml.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
> Enforce JDK 1.7 for storm-kafka
> -------------------------------

> Key: STORM-679
> URL: https://issues.apache.org/jira/browse/STORM-679
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-kafka
> Affects Versions: 0.10.0
> Reporter: jayapriya surendran
> Assignee: jayapriya surendran
> Priority: Minor
>
> ExponentialBackoffMsgRetryManager.java uses Long.compare(long1, long2) method
> which is specific to JDK 7.
> {code}
> public int compare(MessageRetryRecord record1, MessageRetryRecord record2) {
> return Long.compare(record1.retryTimeUTC, record2.retryTimeUTC);
> }
> {code}
> As per the comment in this commit
> https://github.com/apache/storm/commit/fd066985a74c3140f61a465cfc49c83a6ddfa713
> we should enforce JDK 1.7 as the minimum requirement for storm-kafka.
> Alternate fix is to change Long.compare() method to Long.compareTo() which is
> compatible with JDK 1.6.
