Subject [jira] [Commented] (FLINK-8265) Missing jackson dependency for flink-mesos
Date Thu, 14 Dec 2017 21:13:01 GMT

    [ https://issues.apache.org/jira/browse/FLINK-8265?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16291605#comment-16291605
] 

Jared Stehler commented on FLINK-8265:
--------------------------------------

There is a shaded jackson class with jackson2 in the package, but none with the path shown.
It seems like there is a missing include for jackson here in the flink-mesos pom?

{code}
							<artifactSet>
								<includes combine.children="append">
									<include>com.google.protobuf:protobuf-java</include>
									<include>org.apache.mesos:mesos</include>
									<include>com.netflix.fenzo:fenzo-core</include>
								</includes>
							</artifactSet>
							<relocations combine.children="append">
								<relocation>
									<pattern>com.google.protobuf</pattern>
									<shadedPattern>org.apache.flink.mesos.shaded.com.google.protobuf</shadedPattern>
								</relocation>
								<relocation>
									<pattern>com.fasterxml.jackson</pattern>
									<shadedPattern>org.apache.flink.mesos.shaded.com.fasterxml.jackson</shadedPattern>
								</relocation>
							</relocations>
{code}

I was able as a workaround to build a simple shaded jackson deps jar relocated to "org.apache.flink.mesos.shaded.com.fasterxml.jackson"
and adding that to my /lib.

> The Jackson library that is required by Fenzo is missing from the Flink distribution
jar-file.
