https://issues.apache.org/jira/browse/HBASE-26196 Usecase: ``` TableName tableName = TableName.valueOf("table"); Configuration conf = job.getConfiguration(); // assume cluster B is secure Configuration clusterB = HBaseConfiguration.createClusterConf( conf, "hbase-b-1.example.com,hbase-b-2.example.com,hbase-b-3.example.com:2181:/hbase-b"); clusterB.set(User.HBASE_SECURITY_CONF_KEY, "kerberos"); // configure others too like MASTER_KRB_PRINCIPAL, REGIONSERVER_KRB_PRINCIPAL and so on // hack. TableMapReduceUtil.initCredentialsForCluster create UserProvider using job's configuration // Thus if User.HBASE_SECURITY_CONF_KEY is simple, token isn't obtained conf.set(User.HBASE_SECURITY_CONF_KEY, "kerberos"); TableMapReduceUtil.initCredentialsForCluster(job, clusterB); // assume cluster A isn't secure conf.set(HConstants.ZOOKEEPER_QUORUM, "hbase-a-1.example.com,hbase-a-2.example.com,hbase-a-3.example.com"); conf.setInt(HConstants.ZOOKEEPER_CLIENT_PORT, 2181); conf.set(HConstants.ZOOKEEPER_ZNODE_PARENT, "/hbase-a"); conf.set(User.HBASE_SECURITY_CONF_KEY, "simple"); TableMapReduceUtil.initTableMapperJob(tableName, scanner, Mapper.class, ImmutableBytesWritable.class, Put.class, job); try (Connection con = ConnectionFactory.createConnection(clusterB); Table table = con.getTable(tableName); RegionLocator regionLocator = con.getRegionLocator(tableName)) { HFileOutputFormat2.configureIncrementalLoad(job, table, regionLocator); conf.set(HFileOutputFormat2.REMOTE_CLUSTER_CONF_PREFIX + User.HBASE_SECURITY_CONF_KEY, "kerberos"); } return job.waitForCompletion(true) ? 0 : 1; ``` -- This is an automated message from the Apache Git Service.
