…heir names on Windows.
ABFS built list-status entry paths with File.separator, which is a
backslash on Windows. Path("\name:x") then treats "\name" as a URI
scheme, so listing a directory whose children contain a colon failed
with URISyntaxException. The separator here is part of an ABFS/URI
path, not a local filesystem path, so use a forward slash
unconditionally.

@Hexiaoqiao @shfshihuafeng would you have time to take a look at this backport? It is a one-line ABFS fix for HDFS-17881.

Sorry, I'm not working on Hadoop any more, taking a break before going on a different direction in my life.

Description of PR
Backport of HDFS-17881 to
branch-3.5, targeting 3.5.1. Trunk PR: #8536.AbfsClient.getVersionedFileStatusFromEntry()built the entry path asnew Path(File.separator + entry.name()). On WindowsFile.separatoris abackslash, so for a child entry named
FestSpecial:the string handed toPathis\FestSpecial:.Pathlooks for the first:before the first/; finding no/, it treats\FestSpecialas a URI scheme and listingfails:
The separator here is part of an ABFS/URI path, not a local filesystem path,
so it must always be
/. Linux was unaffected becauseFile.separatorisalready
/there.This is a clean cherry-pick of the trunk commit — the patch is identical.
How was this patch tested?
New unit test
TestAbfsClient#testGetVersionedFileStatusFromEntryUsesForwardSlash,asserting the entry path is built with
/independently of the platform'sFile.separator. It fails on Windows before the fix and is a regression guardon every platform afterwards. Yetus reported
