Zhe Zhang updated HDFS-10745:
-----------------------------
Attachment: HDFS-10745-branch-2.7.01.patch
I figured that HDFS-8200 and HDFS-9621 should be backported first to support
this backport. Attaching rebased branch-2.7 patch.
The most messy part of the backport is around {{startFile}} because of the
{{FSDirWriteFileOp}} refactor. The previous version of the branch-2.7 patch
caused a lot of failures mainly because it used a wrong version of
{{getFileInfo}}.
{code}
stat = FSDirStatAndListingOp.getFileInfo(
dir, src, false, FSDirectory.isReservedRawName(srcArg));
{code}
> Directly resolve paths into INodesInPath

> The intermediate resolution to a string, only to be decomposed by
> {{INodesInPath}} back into a byte[][] can be eliminated by resolving directly
> to an IIP. The IIP will contain the resolved path if required.
