嗨，我正在使用独立的hbase，我想测试它的火花。我的机器上没有hadoop。带Spark的独立HBase，HBaseTest.scala给出错误
当我试图让使用HBaseTest.scala（Scala中的例子） 表的计数我得到以下错误：

我不能够在这里找出什么问题。 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()
}
}
我面临同样的问题，你有没有发现它的灵魂？ –
