[jira] [Resolved] (HADOOP-9474) fs -put command doesn't work if
selecting certain files from a local folder

Andras Bokor resolved HADOOP-9474.

Resolution: Not A Bug

> Key: HADOOP-9474
> URL: https://issues.apache.org/jira/browse/HADOOP-9474
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 1.1.2
> Reporter: Glen Mazza
>
> The following four commands (a) - (d) were run sequentially. From (a) - (c) HDFS folder "inputABC" does not yet exist.
> (a) and (b) are improperly refusing to put the files from conf/*.xml into inputABC because folder inputABC doesn't yet exist. However, in (c) when I make the same request except with just "conf" (and not "conf/*.xml") HDFS will correctly create inputABC and copy the folders over. We see that inputABC now exists in (d) when I subsequently try to copy the conf/*.xml folders, it correctly complains that the files already exist there.
> IOW, I can put "conf" into a nonexisting HDFS folder and fs will create the folder for me, but I can't do the same with "conf/*.xml" -- but the latter should work equally as well. The problem appears to be in org.apache.hadoop.fs.FileUtil, line 176, which properly routes "conf" to have its files copied but will have "conf/*.xml" subsequently return a "nonexisting folder" error.
