hbase shell：TypeError：无法复制NilClass [英] hbase shell: TypeError: can't dup NilClass

问题描述

在尝试启动 hbase shell 时出现此奇怪错误。

 ＃hbase shell 
 TypeError：can not dup NilClass 
 dup at org / jruby / RubyKernel.java：1940 
初始化文件：/usr/lib/hbase/lib/jruby-complete-1.6.8.jar！/META-INF/jruby.home/lib/ruby/1.8 /pathname.rb:212 
（root）at /usr/lib/hbase/bin/../bin/hirb.rb:41 
  

有没有发生过任何人？我该如何解决这个问题？

解决方案

我遇到了类似的异常。原因是因为，我的老版本的hbase实际上指向了路径。所以当我输入hbase shell时，会调用旧的hbase。我正确纠正了我的环境变量并将其指向新的hbase，然后工作正常。
所以你的也是类似的问题。

  export HBASE_HOME =<将正确的路径添加到hbase-dir> 
 export PATH = $ HBASE_HOME / bin：$ PATH 
  

这对我有用。 p>

I'm getting this strange error when trying to launch hbase shell. I'm using CDH5.

# hbase shell
TypeError: can't dup NilClass
         dup at org/jruby/RubyKernel.java:1940
  initialize at file:/usr/lib/hbase/lib/jruby-complete-1.6.8.jar!/META-INF/jruby.home/lib/ruby/1.8/pathname.rb:212
      (root) at /usr/lib/hbase/bin/../bin/hirb.rb:41

Has it occurred to anyone? How can I resolve this?

解决方案

I faced a similar exception. The reason was because, my older version of hbase was actually pointed in the path. so when I type hbase shell, the older hbase was invoked. I corrected my environment variables properly and pointed it to new hbase, then it was working fine. So yours will be also similar issue.

export HBASE_HOME=<add the proper path to hbase-dir>
export PATH=$HBASE_HOME/bin:$PATH

This worked for me.
