Oozie Java Action - Hbase : Error

padmanabhan5789 — Wed, 22 Feb 2017 01:49:16 GMT

I'm running a test hbase java program via oozie java action. The following error is encountered :

Error, 
java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration
	at org.apache.oozie.action.hadoop.HbaseCredentials.copyHbaseConfToJobConf(HbaseCredentials.java:67)

The program runs correctly from command line :

java -cp `hbase classpath` personal_project.HBaseConnector

Is there a way I can pass output of 'hbase classpath' to the oozie java action. I have copied below hbase jars to workflow's lib directory as well.

hbase-common-$HBASE_VERSION.jar
hbase-client-$HBASE_VERSION.jar
hbase-server-$HBASE_VERSION.jar
hbase-protocol-$HBASE_VERSION.jar
hbase-hadoop2-compat-$HBASE_VERSION.jar
htrace-core-*.jar
hive-hbase-handler-$HBASE_VERSION.jar

Following is the java action from workflow.xml :

@Padmanabhan Vijendran Check if ozzie shared lib is configured properly and has right hbase dependencies. If not properly configured you can recreate shared lib using below commands:

/usr/hdp/current/oozie/bin/oozie-setup.sh sharelib create -locallib /usr/hdp/<version>/oozie/oozie-sharelib.tar.gz -fs hdfs://<namenode-host>:8020

oozie admin -oozie http://<oozie-host>:11000/oozie -sharelibupdate

@Ajay I am not an admin to do this. I believe sharelib is properly set. Hive Actions are running fine.

Adding the below Credential properties fixed my issue.

<credentials>
		<credential name="hbase-cred" type="hbase">
			<property>
				<name>hadoop.security.authentication</name>
				<value>kerberos</value>
			</property>
			<property>
				<name>hbase.security.authentication</name>
				<value>kerberos</value>
			</property>
			<property>
				<name>hbase.master.kerberos.principal</name>
				<value>hbase/_HOST@XX.XX.COM</value>
			</property>
			<property>
				<name>hbase.regionserver.kerberos.principal</name>
				<value>hbase/_HOST@XX.XX.COM</value>
			</property>
			<property>
