> Project: Hadoop HDFS

>
> If the name component length is greater than the permitted length, the error
> message points to wrong parent directory for mkdir and touchz.
> Here are examples where the parent directory name is in error message. In
> this example dfs.namenode.fs-limits.max-component-length is set to 19.
> {code}
> hdfs dfs -mkdir /user/hrt_qa/FileNameLength/really_big_name_dir01
> mkdir: The maximum path component name limit of really_big_name_dir01 in
> directory /user/hrt_qa/ is exceeded: limit=19 length=21
> {code}
> The expected value for the directory was _/user/hrt_qa/FileNameLength_. The
> same behavior is observed for touchz
> {code}
> hdfs dfs -touchz /user/hrt_qa/FileNameLength/really_big_name_0004
> touchz: The maximum path component name limit of really_big_name_0004 in
> directory /user/hrt_qa/ is exceeded: limit=19 length=20
> {code}
