Description

RouterClientProtocol#getMountPointStatus will return wrong owner, group and permission for the special path.

 

The mountPoint like this:

Mount Table Entries:

Source        Destinations           Owner    Group   Mode       Quota/Usage
/home         ns1 -> /home           home     home    rwxrwxrwx  NsQuota: -/-, SsQuota: -/-
/home/test1   ns2 -> /home/test1     htest1   htest1  rwxr-xr-x  NsQuota: -/-, SsQuota: -/-
/test1        ns3 -> /test1          test1    test1   rwxrwxrwx  NsQuota: -/-, SsQuota: -/-

 

 

RouterClientProtocol#getMountPointStatus("/home/test1", HdfsFileStatus.EMPTY_NAME, false) will return null, and it is ok.

But RouterClientProtocol#getMountPointStatus("/home/", HdfsFileStatus.EMPTY_NAME, false) returns 0777.

[HdfsLocatedFileStatus{path=null; isDirectory=true; modification_time=1560857909200; access_time=1560857909200; owner=xuzq; group=supergroup; permission=rwxrwxrwx; isSymlink=false; hasAcl=false; isEncrypted=false; isErasureCoded=false}]

 

It is clear that the result should like:

 

[HdfsLocatedFileStatus{path=/home/test1; isDirectory=true; modification_time=2; access_time=2; owner=htest1; group=htest1; permission=rwxr-xr-x; isSymlink=false; hasAcl=false; isEncrypted=false; isErasureCoded=false}]
