我用谷歌搜索了很多来解决这个问题，但没有成功。在解决这个问题的过程中，我做了以下改动：
•根据我的环境更改build.sbt文件中的从属库版本 •增加了几个依赖库“hbase-client”，“hbase-common”＆amp; “HBase的服务器”。
•将“hbase.zookeeper.quorum”值从“quickstart.cloudera”链接到“hbase-site.xml”文件中的“127.0.0.1”。

请帮我解决这个问题。谢谢。

Answer 1

解决了这个问题。需要进行以下更改：

将build.sbt文件中的“hadoop-core”更改为“hadoop-common”。由于在最新的CDH版本中，'hadoop-core'仅由运行MapReduce 1的代码支持。

根据build.sbt中的cloudera 5.8.0兼容性更改所有依赖版本。更新后的 build.sbt 如下所示：

name := "play-sbt-project"  
version := "1.0"  
scalaVersion := "2.10.2"  
resolvers += "Thrift" at "http://people.apache.org/~rawson/repo/"  
resolvers += "Cloudera Repository" at "https://repository.cloudera.com/artifactory/cloudera-repos/"  

libraryDependencies ++= Seq(  
 "org.apache.hadoop" % "hadoop-common" % "2.6.0-cdh5.8.0",  
 "org.apache.hbase" % "hbase" % "1.2.0-cdh5.8.0",  
 "org.apache.hbase" % "hbase-client" % "1.2.0-cdh5.8.0",  
 "org.apache.hbase" % "hbase-common" % "1.2.0-cdh5.8.0",  
 "org.apache.hbase" % "hbase-server" % "1.2.0-cdh5.8.0"  
)

对HBaseConfiguration（）类进行了描述。而是使用create（）方法。我还改变了主代码中的一些逻辑。早些时候我得到HBase中的表格（因为这提出了一些问题，所以我放弃了这个，但我下次会尝试这个），因为我的机制是建立Scala到HBase的连接，所以现在我试图插入新行到已经存在的HBase表。新代码如下所示：

package main.scala

import org.apache.hadoop.conf.Configuration  
import org.apache.hadoop.hbase.HBaseConfiguration  
import org.apache.hadoop.hbase.client.{ConnectionFactory,HTable,Put}  
import org.apache.hadoop.hbase.util.Bytes  

object Hi {  

 def main(args: Array[String]) = {  
 println("Hi!")  
 val conf:Configuration = HBaseConfiguration.create()  
 val table:HTable = new HTable(conf, "emp1")  
 val put1:Put = new Put(Bytes.toBytes("row1"))  
 put1.add(Bytes.toBytes("personal_data"),Bytes.toBytes("qual1"),Bytes.toBytes("val1"))  
 table.put(put1)  
 println("Success")  
 }  
}
