Hi, I managed to solve it There are 2 things need to be done for this to work: First add few jars in the libjars and second add hbase lib to hadoop class path and then it should work. Here are the libjars needed hbase-client.jar,hbase-server.jar,hbase-protocol.jar,hbase-common.jar,htrace-core-2.00.jar pay attention to htrace-core-2.00.jar which is Cloudera jar and I am using hortonworks sandbox 2.2.4.2-2 and need to add the hbase lib to hadoop-env.sh otherwise you wont be able to run the main thread Thank you for your help hope it helps!! ...

OK, I tried the examples and I get the same exception I think it means that the problem is with the deployment.. I don't have a pom I just create a jar and put it with relevant jars and then run it with hadoop jar ... View more

HBase MapReduce job

Here is my code for the driver for mapreduce : public int run(String[] args) throws Exception { // TODO Auto-generated method stub if (args.length!=1){ System.out.println("usage: [input]"); System.exit(-1); } Job job = Job.getInstance(getConf()); job.setJarByClass(HBaseDriver.class); FileInputFormat.addInputPath(job , new Path(args[0])); job.getConfiguration().set(TableOutputFormat.OUTPUT_TABLE, "students"); job.setInputFormatClass(StudentInputFormat.class); job.setMapperClass(HBaseStudentsMapper.class); job.setOutputFormatClass(TableOutputFormat.class); job.setNumReduceTasks(0); returnjob.waitForCompletion(true)? 0 :1; } Looks like the system fails on this line : job.setOutputFormatClass(TableOutputFormat.class); the message is: Exception in thread "main" java.lang.NoClassDefFoundError: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/protobuf/generated/MasterProtos$MasterService$BlockingInterface The interesting thing is that if I comment this line and do some Hbase stuff in the mapper it works. More over I have he hbase-protocol library and I supply it with my libjars command here is how I run the map reduce: hadoop jar mo.jar HBaseDriver -libjars hbase-client.jar,hbase-common.jar,hbase-protocol.jar,htrace-core-2.00.jar,hbase-server.jar input ...
