------------------------------------------------------
I'm sorry, what we said may be different thing.:(
First, while mount point creation，we get the owner from
{code:java}
UserGroupInformation ugi = NameNode.getRemoteUser();
record.setOwnerName(ugi.getShortUserName());
{code}
then it will be overwrite.
{code:java}
// Set ACL info for mount table entry
if (aclInfo.getOwner() != null) {
newEntry.setOwnerName(aclInfo.getOwner());
}
if (aclInfo.getGroup() != null) {
newEntry.setGroupName(aclInfo.getGroup());
}
if (aclInfo.getMode() != null) {
newEntry.setMode(aclInfo.getMode());
}
{code}
Second, my mount table like blew:
!image-2019-08-16-17-16-00-863.png|width=563,height=50!
!image-2019-08-16-17-16-34-325.png|width=552,height=56!
The FsShell LS result does not match my expect, my expect result should be like:
drwxr-xr-x - *mnt_test1 mnt_test1_group* 0 2019-08-15 19:07 /mnt/test1
Your expect result is what? and why? [~hemanthboyina] :)
