Soumitra Sulav created HDDS-784:
-----------------------------------
Summary: ozone fs volume created with non-existing unix user
Key: HDDS-784
URL: https://issues.apache.org/jira/browse/HDDS-784
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Filesystem
Affects Versions: 0.3.0
Reporter: Soumitra Sulav
ozone command to create a volume with owner being any username runs
successfully even if it is not part of unix users.
The command throws a security warning _(security.ShellBasedUnixGroupsMapping)_
but still creates the volume.
As a result we can't list the volume, and volume listing with root returns an
empty string.
ozone cli Command run :
{code:java}
ozone sh volume create testvolume -u=hdfs{code}
