您好&感谢您抽出时间来看看我正在讨论的这个问题。
感谢您的帮助，因为我刚刚开始使用hadoop和nosql。。。
hbase登录：
我开始一个 hbase shell 通过ssh到远程主机并使用hadoop沙盒，然后shell正常启动，但很少出现警告：

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>

然后我键入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]

然后等待了几秒钟，我认为hbase正在尝试通过zookeeper获得连接。
然后我得到以下错误：

这个错误不断重复。
