scala - Cloudera 快速启动 VM CDH5.8.0 中的 Hbase Scala 连接问题

Question

我正在尝试从 Scala 代码连接 HBase，但出现以下错误。

• 主机操作系统是具有 8 GB RAM 和 64 位架构的 Windows 7。英特尔酷睿 i5。
• 我正在使用 Cloudera 快速启动 VM CDH 5.8.0。在我的 Windows 上。
• VM 使用 6GB RAM、2 个处理器和 64 GB 硬盘。
• Cloudera Manager 中运行的服务：

    Hbase  
    HDFS  
    YARN  
    Zookeeper  
    Key-Value Indexer

• Cloudera Manager 中停止的服务：

    Hive
    Hue
    Impala
    Oozie
    Solar
    Spark
    Sqoop 1 Client
    Sqoop 2

• Hbase 版本 1.2.0-cdh5.8.0
• 我的客户端代码仅在 VM 中。
• 创建了sbt 项目。
• 我参考了这个 url https://hbase.apache.org/book.html#scala 来获取 Hbase 与 Scala 的连接。
• 设置类路径。我没有在链接中提到的 CLASSPATH 中提到“/path/to/scala-library.jar”。

$ export CLASSPATH=$CLASSPATH:/usr/lib/hadoop/lib/native:/usr/lib/hbase/lib/native/Linux-amd64-64

• 项目根目录= /home/cloudera/Desktop/play-sbt-project
• 我的/home/cloudera/Desktop/play-sbt-project/build.sbt看起来像这样。我根据我的环境更改了依赖库版本。作为错误故障排除的一部分，我添加了更多依赖项，例如“hbase-client”、“hbase-common”和“hbase-server”，但仍然没有成功。

name := "play-sbt-project"
version := "1.0"
scalaVersion := "2.10.2"
resolvers += "Apache HBase" at "https://repository.apache.org/content/repositories/releases"
resolvers += "Thrift" at "http://people.apache.org/~rawson/repo/"
libraryDependencies ++= Seq(
"org.apache.hadoop" % "hadoop-core" % "1.2.1",
"org.apache.hbase" % "hbase" % "1.2.0",
"org.apache.hbase" % "hbase-client" % "1.2.0",
"org.apache.hbase" % "hbase-common" % "1.2.0",
"org.apache.hbase" % "hbase-server" % "1.2.0"
)

• 我的 Hbase 连接 /home/cloudera/Desktop/play-sbt-project/src/main/scala/pw.scala 的主要代码如下所示

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

object Hi {
def main(args: Array[String]) = {
println("Hi!")
val conf = new HBaseConfiguration()
val connection = ConnectionFactory.createConnection(conf);
val admin = connection.getAdmin();

// list the tables
val listtables=admin.listTables()
listtables.foreach(println)
}
}

• 我的 /etc/hbase/conf/hbase-site.xml 如下所示：

我google了很多来解决这个问题，但没有成功。在解决此问题的过程中，我进行了以下更改：
• 根据我的环境更改了 build.sbt 文件中的依赖库版本
• 添加了更多依赖库“hbase-client”、“hbase-common”和“hbase-server ”。
• 将“hbase-site.xml”文件中的“hbase.zookeeper.quorum”值从“quickstart.cloudera”更改为“127.0.0.1”。

请帮我解决这个问题。谢谢你。

Resolved the issue. There are following changes need to be done:

Change "hadoop-core" to "hadoop-common" inside build.sbt file. Since in latest CDH versions 'hadoop-core' is only supported by code running for MapReduce 1.

Change all the dependecy version as per cloudera 5.8.0 compatibility in build.sbt. Updated build.sbt looks like this:

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"  
)

HBaseConfiguration() class is depricated. Instead use create() method. Also I changed some logic in the main code. Earlier I was getting the tables present in HBase (Since this was giving some issues so I dropped this but I will try this next time), Since my moto is to establish Scala to HBase connectivity so now I am trying to insert new row to the already existing HBase table. New code looks like this:

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")  
 }  
}
