JDBC application on Windows throws error message on winutils. Problem #3 is that the mechanism by which you inform the Hadoop client software where to find winutils.exe is poorly documented and fragile. This makes creating and maintaining test environments that work with all of the Hadoop distros we want to test unnecessarily tedious and error-prone.

Thus, as software developers, we are forced to pick one version and distribute and install it with our software. Problem #1 with winutils.exe is that it is simply missing from many popular distros and/or the client-side software installation for said distros, when supplied, fails to install winutils.exe. My team creates software that runs on Windows and Linux, and winutils.exe is probably responsible for 20% of all issues we encounter, both during development and in the field.
Unfortunately, like many stopgap measures in software, this one has persisted well beyond its expected lifetime and usefulness. Rather than building a DLL that makes native OS calls, the creators of winutils.exe must have decided that it would be more expedient to create an EXE to carry out file system operations in a linux-like fashion. Winutils.exe was apparently created as a stopgap measure to allow Hadoop to 'work' on Windows platforms, because the NativeIO libraries aren't implemented there (edit: even NativeIO probably doesn't cover the operations that winutils.exe is used for).
