Kazuho Fujii updated HDFS-9431:
-------------------------------
Attachment: HDFS-9431.002.patch
Hi, [~liuml07]. Thanks for the comment.
I added some assertions to the test. I think this is enough because the test
expects only that the operation does not fail.
{quote}
the trunk code fails the newly added test because pathname is not a valid DFS
filename?
{quote}
Yes. {{getPathName}} method expects a URI with an absolute path.
> DistributedFileSystem#concat fails if the target path is relative.

> {{DistributedFileSystem#concat}} fails if the target path is relative.
> The method tries to send a relative path to DFSClient at the first call.
> bq. dfs.concat(getPathName(trg), srcsStr);
> But, {{getPathName}} failed. It seems that {{trg}} should be {{absF}} like
> the second call.
> bq. dfs.concat(getPathName(absF), srcsStr);
