@Hexiaoqiao @shfshihuafeng would you have time to take a look at this one? It is a one-line ABFS fix for HDFS-17881. All checks are green: Backports are prepared for the release branches: #8692 (branch-3.5) and Thanks! |

* as noted, I'm not working. taking august off and doing something completely different from mid sept. sorry
only worry about this pr, asking for other branches is a distraction. the backports are just that, backports of whatever is in trunk, and shouldn't be different except where some incompatiblity (like junit) force it. get this one, submit those PRs with a declaration of which azure endpoints you reran the hadoop azure itests against (i.e. |

…hildren folder with colon in 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.

Would be good to test this against a real storage account. May be run some integration test if not already done.

I am not set up to test against msft storage. Anyone who hits problems with azure storage must have an account, and so should be able to get set up for this. please get set up for testing...we can't be getting changes into a cloud storage connector that isn't being tested against that store, as it will ship and regressions not found out until it is actually in production. |

@vt921102 I'm taking an extended break from software dev, though I'm trying to set up hadoop for reproducible builds so we can get a 3.5.1 release out. If @anujmodi2021 cherrypicks this commit into that branch, it'll be included. |

…hildren folder with colon in Windows. (apache#8536) Contributed by Le Van Toan (cherry picked from commit e8783aa) The production change is identical to trunk. TestAbfsClient required adaptation because branch-3.4 is still on JUnit 4 with Assertions.assertThat and Mockito.spy, its AbfsDfsClient constructor takes six arguments, and its AbfsClientContextBuilder has no withFileSystemId.

Description of PR
Fixes HADOOP-19973.
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.Backports: #8692 (branch-3.5), #8693 (branch-3.4).
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
