How was this patch tested?
1.pass all the unit tests: mvn clean compile package install -Drat.skip=true
2.After removing jersey-core from distro/src/main/assembly/hbase-agent.xml and compiling, I reinstalled the Hadoop and HBase cluster, integrated Ranger 2.4, configured and enabled Ranger in hbase-site.xml file as follows:
Set hbase.coprocessor.master.classes to org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor Set hbase.coprocessor.region.classes to org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint,org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor Set hbase.coprocessor.regionserver.classes to org.apache.ranger.authorization.hbase.RangerAuthorizationCoprocessor
After restarting HBase, no more exception messages were observed and the master is running smoothly.
