Akira AJISAKA updated HDFS-8891:
--------------------------------
Attachment: HDFS-8891-test-only-branch-2.6.patch
The regression test passes in branch-2.6. Attaching a
regression-test-only-patch for branch-2.6.
I looked into the source code and I don't see the srcs are into {{HashMap}} and
then converted to an array in branch-2.6. In branch-2.6, the order or the srcs
is kept.
> HDFS concat should keep srcs order
