Additionally, in your build, jackson.version is 1.8.8 because you choose
spark 1.2. In case of spark 1.2, jackson.version is 1.8.8 by default, I think
it's a mistake because jackson.version influence hadoop actually but configured
in spark-1.3 profile, so If you change hadoop-2.4's jackson.version to 1.9.13,
you can build Zeppelin with spark 1.2. and hadoop 2.6
```
mvn clean install -DskipTests -Pspark-1.2 -Phadoop-2.4
-Dhadoop.version=2.6.0 -Pyarn
```
It may works correctly.
