Question

我想在cygwin64上运行hadoop 2.6.1。（后来我也想运行hBsae）问题是，我开始start-dfs.sh，我会得到这个例外：

 15/10/07 21:13:54 ERROR util.Shell: Failed to locate the winutils binary    in the hadoop binary path
java.io.IOException: Could not locate executable null\bin\winutils.exe in the Hadoop binaries.

好的，我知道这是一个众所周知的问题，本论坛中的一些解决方案说明了将HADOOP_HOME添加到环境中的问题。但问题仍然存在。这是我的bash_profile：

的片段

# cygwin path translation

export JAVA_HOME=$(cygpath -u $(cygpath -m -s "${JAVA_HOME}"))
export HADOOP_PREFIX=/home/user/hadoop-2.6.1

export PATH=$PATH:$(cygpath -u $(cygpath -m -s "${JAVA_HOME}\bin")):/home/user/hadoop-2.6.1/bin
export HADOOP_INSTALL=/home/user/hadoop-2.6.1

export HADOOP_HOME=/home/user/hadoop-2.6.1/
export HADOOP_MAPRED_HOME=$HADOOP_INSTALL
export HADOOP_COMMON_HOME=$HADOOP_INSTALL
export HADOOP_HDFS_HOME=$HADOOP_INSTALL
export YARN_HOME=$HADOOP_INSTALL
export HADOOP_COMMON_LIB_NATIVE_DIR=/home/user/hadoop-2.6.1/lib/native
export PATH=$PATH:$HADOOP_INSTALL/sbin
export PATH=$PATH:$HADOOP_INSTALL/bin

echo $HADOOP_HOME也会打印路径。但为什么winutils的路径不完整？或者我有一个可变的变量吗？

问候

您应该在PATH（环境变量）中设置winutils.exe。

麻烦与cygwin和hadoop 2.6.1 - null \ bin \ winutils.exe
