title: How can i read data from Hbase table in Spark?
body: <p>I have a table in Hbase that has the following data in it:</p>
  
  <pre><code>ROW COLUMN+CELL
  1   column=brid:, timestamp=1470047093100, value=a1234
  1   column=custid:, timestamp=1470046713207, value=811411
  2   column=brid:, timestamp=1470047231583, value=a6789
  2   column=custid:, timestamp=1470047156905, value=848727431
  </code></pre>
  
  <p>I am trying to read this data into Spark and then print the data inside the table to the console. My code for accomplishing this is as follows:</p>
  
  <pre><code>val conf = new SparkConf().setAppName("Spark Base").setMaster("local[*]")
  val sc = new SparkContext(conf)
  
  val hbaseConf = HBaseConfiguration.create()
  hbaseConf.set("hbase.zookeeper.quorum", "127.0.0.1")
  hbaseConf.set("hbase.zookeeper.property.clientPort", "5181") 
  hbaseConf.set(TableInputFormat.INPUT_TABLE, "/path/to/custid1") 
  
  val hbaseData = sc.newAPIHadoopRDD(hbaseConf, classOf[TableInputFormat], classOf[ImmutableBytesWritable], classOf[Result])
  
  hbaseData.map(row =&gt; Bytes.toString(row._2.getValue("custid".getBytes(), "brid".getBytes()))).collect().foreach(println)
  println("Number of Records found : " + hbaseData.count())
  sc.stop()
  </code></pre>
  
  <p>The output looks like this:</p>
  
  <pre><code>null
  null
  Number of Records found : 2
  </code></pre>
  
  <p>The count is correct as there are only two records in the Hbase table. But why is it displaying the values as null? And, how can i get it to actually print the values inside the table?</p>
  
  <p>Thanks. </p>
