Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The "WindowsProblems" page has been changed by SteveLoughran: https://wiki.apache.org/hadoop/WindowsProblems Comment: wiki page on windows problems (esp. WINUTILS.EXE) New page: = Problems running Hadoop on Windows = Hadoop requires native libraries on Windows to work properly -that includes to access 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, `%HADOOP_HOME%\BIN\WINUTILS.EXE` must be locatable. If it is not, Hadoop or an application built on top of Hadoop will fail. == How to fix a missing WINUTILS.EXE == You can fix this problem in two ways 1. Install a full native windows Hadoop version. The ASF does not currently (September 2015) release such a version; releases are available externally. 1. Get the `WINUTILS.EXE` binary from a Hadoop redistribution. There is a copy of this for Hadoop 2.6 [[on github|https://github.com/steveloughran/clusterconfigs/tree/master/clusters/morzine/hadoop_home]]. 1. Set the environment variable `%HADOOP_HOME%` to point to the directory above the `BIN` dir containing `WINUTILS.EXE`.
