您好，感谢您花时间查看我遇到的这个问题。

感谢您的帮助，因为我刚开始使用 hadoop 和 noSQL...

HBase 登录：

我通过 ssh 启动一个hbase shell 到远程主机并使用 hadoop 沙箱，然后 shell 正常启动，几乎没有警告：

2015-02-22 23:00:17,892 INFO  [main] Configuration.deprecation: hadoop.native.lib is deprecated. Instead, use io.native.lib.available
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 0.98.4.2.2.0.0-2041-hadoop2, r18e3e58ae6ca5ef5e9c60e3129a1089a8656f91d, Wed Nov 19 15:10:28 EST 2014

hbase(main):001:0>

然后我输入 cmd list

hbase(main):001:0> list

我得到以下信息

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/hdp/2.2.0.0-2041/hadoop/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/hdp/2.2.0.0-2041/zookeeper/lib/slf4j-log4j12-1.6.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

然后等待几秒钟，我认为 HBase 正在尝试通过 zookeeper 获取连接。

然后我得到以下错误：

并且此错误不断重复。

【问题讨论】：

检查zookeeper、regionserver和hmaster是否启动？

【解决方案1】：

我通过在 8080 端口访问 Ambari 并重置所有 HBase 服务解决了这个问题。希望这可以帮助某人！
