Winutils Exe Hadoop


  • HADOOP-11003 org.apache.hadoop.util.Shell should not take a dependency on binaries being deployed when used as a library Resolved HADOOP-10775 Shell operations to fail with meaningful errors on windows if winutils.exe not found.
  • Hadoop requires native libraries on Windows to work properly -that includes accessing the file:// filesystem, where Hadoop uses some Windows APIs to implement posix-like file access permissions. This is implemented in HADOOP.DLL and WINUTILS.EXE. In particular,%HADOOPHOME% BIN WINUTILS.EXE must be locatable.
  • Winutils.exe -help Usage: hadoop bin winutils.exe command. Provide basic command line utilities for Hadoop on Windows. The available commands and their usages are: chmod Change file mode bits. Usage: chmod OPTION OCTAL-MODE FILE or: chmod OPTION MODE FILE Change the mode of the FILE to MODE.

I solved this and it worked for me, hope it would help. It's a very small mistake I made - I saved the winutils executable as 'winutils.exe' instead of just winutils. So when the variable gets resolved it's been resolving to winutils.exe.exe which is nowhere in the Hadoop binaries. I removed that '.exe' and triggered the shell, it worked.

I have not only needed to point HADOOP_HOME to extracted directory [path], but also provide system property -Djava.library.path=[path]bin to load native libs (dll).
