My OS is OS X 10.11.6. I'm running Spark 2.0, Zeppelin 0.6, Scala 2.11
When I run this code in Zeppelin I get an exception from Jackson. When I run this code in spark-shell - no exception.
val filestream = ssc.textFileStream("/Users/davidlaxer/first-edition/ch06")

The dependency-reduced-pom.xml in spark-core shows version 2.6.5
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.6.5</version>

Zeppelin was built with the following parameters:
$ mvn clean package -Pspark-2.0 -Phadoop-2.4 -Pyarn -Ppyspark -Psparkr -Pscala-2.11 -DskipTests
Generating the dependency tree in Zeppelin and in Spark showed all the jackson-databind references as 2.6.5.
$ mvn dependency:tree -Dverbose
shows [INFO] +- com.fasterxml.jackson.core:jackson-databind:jar:2.6.5:compile
I tried deleting ~/.m2/repository/com/fasterxml and rebuilding Spark and Zeppelin.
Here's my $PATH:

Any ideas why I'm picking up version 2.5.3?
回答1:
Replacing the jackson jars (2.5.x version) in './zeppelin-zengine/target/lib/' and './zeppelin-server/target/lib/' with the following version will solve the problem.
jackson-databind-2.6.5.jar jackson-core-2.6.5.jar jackson-annotations-2.6.5.jar
回答2:
you can use $SPARK_HOME/jars/ jackson-databind-2.6.5.jar jackson-core-2.6.5.jar jackson-annotations-2.6.5.jar to replace old version jars ofr $ZEPPELIN_HOME/lib
