启动Hbase：cygpath：不能转换空路径 [英] Starting Hbase : cygpath: can't convert empty path

问题描述

我希望有人可以帮我解决这个问题：

I hope somebody can help me with this problemoo:

启动hbase，得到这个错误：

Starting hbase, I get this error:

$ ./start-hbase.sh
cygpath: can't convert empty path
cygpath: can't convert empty path
soporte@localhost's password:
localhost: starting zookeeper, logging to /usr/local/hbase-0.90.4/bin/../logs/hbase-CNEOSYLAP-zookeeper-CNEOSYLAP.out
localhost: cygpath: can't convert empty path
starting master, logging to /usr/local/hbase-0.90.4/bin/../logs/hbase-CNEOSYLAP-master-CNEOSYLAP.out
cygpath: can't convert empty path
soporte@localhost's password:
localhost: starting regionserver, logging to /usr/local/hbase-0.90.4/bin/../logs/hbase-CNEOSYLAP-regionserver-CNEOSYLAP.out
localhost: cygpath: can't convert empty path

此错误只发生在hbase-0.90。 4和hbase-0.90.6，但不会发生在hbase-0.94.9。我使用Windows 7 x64和CygWin设置2.774。

This error only happens with hbase-0.90.4 and hbase-0.90.6 but is not happening with hbase-0.94.9. I am using Windows 7 x64 and CygWin setup 2.774.

注意1：我按照在Windows上安装HBase 和此处
注意2：重要的是我设置hbase-0.90.X因为后来我会使用Nutch 2.2.1

Note 1 : I was following instructions from Installing HBase on Windows and here Note 2 : It is important to me setting up hbase-0.90.X because later i will use Nutch 2.2.1

感谢

推荐答案

也许在将unix风格路径转换为windows风格路径时，cygpath或路径中的一些问题实际上是空的。记住cygpath是一个cygwin实用程序，将unix样式文件路径转换为Windows样式文件路径，反之亦然。我个人不完全相信这一点。所以，请确保你不面对这些种种问题。为了顺利运行，我想建议一些事情：

Perhaps some problem in the conversion of unix style paths into windows style path by cygpath or the path is actually empty. Remember cygpath is a cygwin utility that converts unix style file paths into windows style file paths, and vice versa. I personally don't trust this completely. So, please make sure that you are not facing those kinda issues. For a smooth functioning, I would like to suggest a couple of things though :

• 修改行＃export HBASE_CLASSPATH = 在 hbase-env.sh 文件中：
  export HBASE_CLASSPATH = / cygdrive / c / programs / hbase-0.90.4 / lib /


• 您的hbse-site.xml中的属性 hbase.rootdir 符合您的cygwin环境：
  像 file： // C：/ cygwin / root / tmp / hbase / data

• Modify the line # export HBASE_CLASSPATH= in hbase-env.sh file as per your environment : export HBASE_CLASSPATH=/cygdrive/c/programs/hbase-0.90.4/lib/
• The property hbase.rootdir in your hbse-site.xml is in terms with your cygwin environment : Something like file:///C:/cygwin/root/tmp/hbase/data

不知怎的，我觉得使用Hadoop / HBase窗口总是一种痛苦。你可以通过自己一个Linux盒子（如果可能）或使用一些虚拟机来避免这些问题。

Somehow I feel that using Hadoop/HBase on windows is always a pain. You can avoid these problems by getting yourself a Linux box(if possible) or make use of some VM.

HTH

P。 S.：您的Hadoop运行正常（如果有）？

P. S. : Is your Hadoop running fine(if you have it)?

编辑：

如果不存在，请在 hbase 目录中的 hbase 文件中添加以下行：

Add these lines in you hbase file under hbase-0.90.4/bin directory, if not present :

# cygwin path translation
if $cygwin; then
  CLASSPATH=`cygpath -p -w "$CLASSPATH"`
  HBASE_HOME=`cygpath -d "$HBASE_HOME"`
  HBASE_LOG_DIR=`cygpath -d "$HBASE_LOG_DIR"`

我现在没有更早的版本，所以我可以交叉检查。

I do not have older releases right now with me so that I can crosscheck.
