Steve Loughran created HADOOP-11285: ---------------------------------------
Summary: 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
