----------------------------------
Summary: Error Message points to wrong parent directory in case of
path component name length error
Key: HDFS-8153
URL: https://issues.apache.org/jira/browse/HDFS-8153
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.5.2
Reporter: Anu Engineer
Assignee: Anu Engineer
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}
