Chris Nauroth commented on HDFS-6531:
-------------------------------------
Linking to HADOOP-9590, which tracks our use cases for calling the new file
APIs introduced in JDK7. With JDK7, we could potentially use {{Files#delete}},
which throws an exception with details if the delete fails. This would reduce
our native code footprint.
http://docs.oracle.com/javase/7/docs/api/java/nio/file/Files.html#delete(java.nio.file.Path)
> Create a native api to delete file, like the renameTo method in NativeIO, for
> better error reporting

> Key: HDFS-6531
> URL: https://issues.apache.org/jira/browse/HDFS-6531
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.4.0
> Reporter: Yongjun Zhang
> Assignee: Yongjun Zhang
>
> File.delete() returns boolean to indicate success or failure.
> As a follow-up of HDFS-6499, filing this jira to provide a native API to
> delete file, like the renameTo method in NativeIO. So caller can tell better
> what's the reason of failure.
> And fix FileJournalManager etc places for better error reporting.
> Thanks [~atm] for reviewing the fix of HDFS-6499 and pointing out this issue.
