hadoop - hbase 未以伪分布式模式运行

Question

我使用的是 Hbase 版本 0.94.8 和 hadoop 版本 2.4.0 。在伪分布式模式下运行 Hbase 时，在检查 master 状态时出现以下错误，

访问/master-status 时出现问题。原因:

org.apache.hadoop.net.NetUtils.getInputStream(Ljava/net/Socket;)Lorg/apache/hadoop/net/SocketInputWrapper;

原因:

java.lang.NoSuchMethodError: org.apache.hadoop.net.NetUtils.getInputStream(Ljava/net/Socket;)Lorg/apache/hadoop/net/SocketInputWrapper;

Answer 1

Hbase - 0.94.8 和 Hadoop - 2.4.0 被 hbase.org 列为未测试。错误原因可能是* 版本兼容性问题*。因为 Hbase 依赖于 Hadoop jar。

Hbase官方文档站点提供了hadoop-hbase version compatability matrix .请引用并选择支持的 Hadoop 和 Hbase 版本。
