synchronize the Tez configurations on all nodes, and restart hiveserver2, it should work fine.

I have found the reason for the problem. I changed the FQDN to lowercase, then it works ok. Thank you for your reply

I have installed Ambari 2.6.0.0 version with HDP 2.6.3 and added some of the services.
But while enabling Kerberos I am facing one weird issue. The error log is: Traceback (most recent call last):

Zeppelin since version 0.6, has provided support for R Interpreter.
By default, the R Interpreter appears as two Zeppelin Interpreters, %r and %knitr.
To run Zeppelin with the R Interpreter, some environment variables must be set: R (3.0+) JAVA_HOME (Oracle JDK 1.7+) SPARK_HOME (The best way to do this is by editing conf/zeppelin-env.sh. If it is not set, the R Interpreter will not be able to interface with Spark.You should also copy conf/zeppelin-site.xml.template to conf/zeppelin-site.xml. That will ensure that Zeppelin sees the R Interpreter the first time it starts up.)
Then, clone the Zeppelin repository and build it with options: >git clone https://github.com/apache/zeppelin.git
# enable the "r" and "sparkr" profile
>mvn clean install -e -DskipTests -Dspark.version={spark_version} -Dhadoop.version={hadoop_version} -Pr -Psparkr -Pvendor-repo -Pexamples -Drat.skip=true -Dcheckstyle.skip=true -Dcobertura.skip=true
And next, install SparkR package. In Spark 1.6 or earlier, the SparkR need to manually install. >cd $SPARK_HOME
>./R/install-dev.sh
Now, you can starting Apache Zeppelin with command line: >cd $ZEPPELIN_HOME
>bin/zeppelin-daemon.sh start -e
After successful start, visit http://localhost:8080 with your web browser. And you can execute commands as in the CLI.
