Andrew Purtell commented on HBASE-15200:
----------------------------------------
I can drop the slash, makes sense it's an environmental thing. The reason I did
that was with startsWith we could make an accidental match without a
terminating character. I can look into utility classes for parsing Kerberos
names and extracting the short name. Hadoop probably has something.
I can give you a zkcli listing of a test environment but not from internal
systems, so probably not useful.
> ZooKeeper znode ACL checks should only compare the shortname

> After HBASE-13768 we check at startup in secure configurations if our znodes
> have the correct ACLs. However when checking the ACL we compare the Kerberos
> fullname, which includes the host component. We should only compare the
> shortname, the principal. Otherwise in a multimaster configuration we will
> unnecessarily reset ACLs whenever any master running on a host other than the
> one that initialized the ACLs makes the check. You can imagine this happening
> multiple times in a rolling restart scenario.
