我正在尝试使用示例代码将数据从spark DataFrame保存到HBase。 我不知道我哪里出错但代码不适合我。
下面是我试过的代码。我能够获得现有表的RDD，但无法保存它。我尝试了几种方法，我已经提到了。
代码：
import scala.reflect.runtime.universe
import org.apache.hadoop.fs.Path
import org.apache.hadoop.hbase.HBaseConfiguration
import org.apache.hadoop.hbase.mapreduce.TableInputFormat
import org.apache.spark.SparkConf
import org.apache.spark.SparkContext
import org.apache.spark.sql.SQLContext
import org.apache.spark.sql.SaveMode
case class Person(id: String, name: String)
object PheonixTest extends App {
val conf = new SparkConf;
conf.setMaster("local");
conf.setAppName("test")
val sc = new SparkContext(conf)
val sqlContext = new SQLContext(sc);
val hbaseConf = HBaseConfiguration.create()
hbaseConf.set(TableInputFormat.INPUT_TABLE, "table1")
hbaseConf.addResource(new Path("/Users/srini/softwares/hbase-1.1.2/conf/hbase-site.xml"));
import org.apache.phoenix.spark._;
val phDf = sqlContext.phoenixTableAsDataFrame("table1", Array("id", "name"), conf = hbaseConf)
println("===========>>>>>>>>>>>>>>>>>> " + phDf.show());
val rdd = sc.parallelize(Seq("sr,Srini","sr2,Srini2"))
import sqlContext.implicits._;
val df = rdd.map { x => {val array = x.split(","); Person(array(0), array(1))} }.toDF;
//df.write.format("org.apache.phoenix.spark").mode("overwrite") .option("table", "table1").option("zkUrl", "localhost:2181").save()
//df.rdd.saveToP
df.save("org.apache.phoenix.spark", SaveMode.Overwrite, Map("table" -> "table1", "zkUrl" -> "localhost:2181"))
sc.stop()
}

答案 0 :(得分：-1)
我注意到两个问题
Zk url。如果您确定zookeeper在本地运行，请使用下面的条目更新您的hosts文件，并将主机名传递给HBaseConfiguration。
=> App running at: http://localhost:3000/

Phoenix默认情况下大写您的表名和列。因此，将上面的代码更改为
ipaddress hostname
