Answer 1

your job is attempting to read an input file from:

 hdfs://HadoopMaster:54310/user/hduser/csvtable

you should verify that this file exists on HDFS using the hadoop shell tools :

hadoop fs -ls /user/hduser/csvtable

my guess is that your file hasn't been loaded onto HDFS.

Answer 2

The problem why you are directing to path hdfs://HadoopMaster:54310/user/hduser/csvtable instead of csvtable is. 1) Add your Hbase jars into Hadoop class path because your Map reduce doesn't by default configure to hbase jars. 2) GO to hadoop-ev.sh and edit Hadoop_classpath and add all your hbase jars in it. hope it might work now
