Question

我最近安装了用

编译的hadoop-2.4.0和hbase-0.95.18

sudo mvn clean package assembly:assembly -DskipTests -Dhadoop.profile=2.4

使用下面的pom.xml选项。

<protobuf.version>2.5.0</protobuf.version>

和

<id>hadoop-2.4</id>
  <activation>
    <property>
      <name>hadoop.profile</name>
      <value>2.4</value>
    </property>
  </activation>
  <properties>
    <hadoop.version>2.4.0</hadoop.version>
    <slf4j.version>1.7.5</slf4j.version>

这是我的hbase-site.xml信息。

<configuration>
   <property>
      <name>hbase.rootdir</name>
      <value>hdfs://big7:54310/hbase</value>
   </property>
   <property>
      <name>dfs.replication</name>
      <value>3</value>
   </property>
   <property>
      <name>hbase.cluster.distributed</name>
      <value>true</value>
   </property>
   <property>
      <name>hbase.zookeeper.quorum</name>
      <value>big11,big1,big4</value>
   </property>
   <property>
      <name>hbase.zookeeper.property.clientPort</name>
      <value>2222</value>
   </property>
   <property>
      <name>hbase.zookeeper.property.dataDir</name>
      <value>/home/hduser/hadoop/zookeeper</value>
   </property>
   <property>
      <name>hbase.cluster.distributed</name>
      <value>true</value>
   </property>
</configuration>

HMaster＆amp; Zookeepers正在成功启动，但区域服务器尚未启动。我在主日志中遇到了以下错误。

有人可以帮我解决这个问题吗？

Answer 1

有两个使用2.4.0编译的.proto文件

$ HBASE_HOME / SRC /主/ protobuf的/ ErrorHandling.proto $ HBASE_HOME / src / main / protobuf / hbase.proto

由于您更改了protobuf.version，您是否使用protobuf-compiler版本2.5.0从.proto文件重新生成.java文件。这可能是问题之一。

您可以使用以下步骤执行此操作。

安装protobuf-compiler版本2.5.0
在$ HBASE_HOME / src / main / protobuf文件夹中运行以下命令 -

$＆gt; protoc -I./ --java_out = src / main / java ErrorHandling.proto

$＆gt; protoc -I./ --java_out = src / main / java hbase.proto
重新编译hbase并启动服务器。

您可以按照here进行讨论，了解更多信息。
