Subject [jira] [Commented] (HDFS-8153) Error Message points to wrong parent directory in case of path component name length error

Anu Engineer commented on HDFS-8153:
------------------------------------

I re-ran these tests on my local machine and they did pass. The error on these test says Time
out, and it quite possible that the failure is due to test infra issues.

> 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}
