Anoop Sam John commented on HBASE-10005:
----------------------------------------
While doing the clearAuths we get the current Auths for the given user and
validate whether removing auth is already present for the user. This get
happens from the cache. The cache update happens via zk data changed event and
this thread can be bit late some times.
In test we 1st add auths and immediately clear some of them. When the
clearAuths reaches the cache update might not have happened yet!!
Changed the code so that it gets the current auths for the user from
hbase:labels table and not from cache. Any way these admin ops for the labels
will not happen frequently.
> TestVisibilityLabels fails occasionally
