> FileUtil operations don't check for native lib loaded on windows; fails with
> NPE
> --------------------------------------------------------------------------------
>
> Key: HADOOP-11285
> URL: https://issues.apache.org/jira/browse/HADOOP-11285
> Project: Hadoop Common
> Issue Type: Bug
> Components: util
> Affects Versions: 2.6.0
> Environment: windows
> Reporter: Steve Loughran
>
> On windows {{FileUtil.canRead()}} and the like requires the native APIs (at
> least until a migration to java 7 APIs). The methods do not, however, call
> {{NativeIO.isAvailable()}} to verify the native libs are there. As a result,
> the calls fail with less useful stack traces.
> if Java 7 allows all of these calls to be replaced, then this is a non-issue
> If not, I propose some {{verifyAvailableOnWindows()}} method which triggers
> an exception; one which includes some hints about the problem —perhaps a URL
> to a wiki page on the topic
