Review request for Ambari, Andrew Onischuk, Dmytro Sen, and Sumit Mohanty.
Bugs: AMBARI-7739
https://issues.apache.org/jira/browse/AMBARI-7739
Repository: ambari
Description
-------
Create an Ambari 1.7.0 cluster with HDP 2.2.1, and install HDFS, Tez, MR, Hive,
Zookeeper.
After switching the hive.execution.engine from "mr" to "tez", attempting to run
the hive shell generates an error.
Logging initialized using configuration in
file:/etc/hive/conf.server/hive-log4j.properties
Exception in thread "main" java.lang.RuntimeException:

Testing
-------
Deployed an HDP 2.2.1 cluster and switched the execution engine to tez.
Then changed the following properties to coincide with the changed files.
HDFS => hadoop-env =
{
...
if [[ -d "/usr/hdp/current/tez-client" && -d "/etc/tez/conf/" ]]; then
# When using versioned RPMs, the tez-client will be a symlink to the current
folder of tez in HDP.
export
HADOOP_CLASSPATH=${HADOOP_CLASSPATH}:/usr/hdp/current/tez-client/:/usr/hdp/current/tez-client/lib/:/etc/tez/conf/
fi
# Setting path to hdfs command line
export HADOOP_LIBEXEC_DIR={{hadoop_libexec_dir}}
# Mostly required for hadoop 2.0
export
JAVA_LIBRARY_PATH=${JAVA_LIBRARY_PATH}:/usr/hdp/current/hadoop-client/lib/native/Linux-amd64-64
...
}
Hive => hive-env =
{
...
if [ "${HIVE_AUX_JARS_PATH}" != "" ]; then
export HIVE_AUX_JARS_PATH=${HIVE_AUX_JARS_PATH}
elif [ -d "/usr/hdp/current/hive-webhcat/share/hcatalog" ]; then
export HIVE_AUX_JARS_PATH=/usr/hdp/current/hive-webhcat/share/hcatalog
fi
...
}
Tez => tez.lib.uris = hdfs:///apps/tez/tez.tar.gz
After restarting the services, ran the following commands to simulate the
behavior of the scripts during the installation of Hadoop.
export TEZ_CONF_DIR=/etc/tez/conf
export TEZ_JARS=/usr/hdp/current/tez-client/*:/usr/hdp/current/tez-client/lib/*
export HADOOP_CLASSPATH=$TEZ_CONF_DIR:$TEZ_JARS:$HADOOP_CLASSPATH
Then ran
su - hive
hive
And was able to get the hive shell to start.
Also ran unit tests,
