Standalone HBase with Spark, HBaseTest.scala is giving error - scala

Question

Hi I am using standalone hbase and I want to test spark on it. There is no hadoop on my machine.
when I try to get count of a table using HBaseTest.scala (in scala examples)
I get following error:

I am not able to figure out whats the issue here.
HBaseTest.scala:
object HBaseTest {
def main(args: Array[String]) {
val sparkConf = new SparkConf().setAppName("HBaseTest").setMaster("local")
val sc = new SparkContext(sparkConf)
val conf = HBaseConfiguration.create()
// Other options for configuring scan behavior are available. More information available at
// http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/mapreduce/TableInputFormat.html
conf.set("zookeeper.znode.parent", "/hbase-unsecure")
conf.set("hbase.zookeeper.quorum", "localhost")
conf.set("hbase.zookeeper.property.clientPort","2181")
conf.addResource(new Path("/usr/lib/hbase/hbase-0.94.8/conf/hbase-site.xml"))
conf.set(TableInputFormat.INPUT_TABLE,"test")
// Initialize hBase table if necessary
val admin = new HBaseAdmin(conf)
if (!admin.isTableAvailable("test")) {
print ("inside if statement")
val tableDesc = new HTableDescriptor(TableName.valueOf("test"))
admin.createTable(tableDesc)
}
val hBaseRDD = sc.newAPIHadoopRDD(conf, classOf[TableInputFormat],
classOf[org.apache.hadoop.hbase.io.ImmutableBytesWritable],
classOf[org.apache.hadoop.hbase.client.Result])
hBaseRDD.count()
sc.stop()
}
}

You ar using TableInputFormat class as input format. TableInputFormat class is belong to hadoop Map-reduce API. You need to install hadoop for using TableInputFormat.
