--------------------------------------
Summary: Restrict the universe of labels and authorizations to
[A-Za-z0-9\_][A-Za-z0-9\_\-]*
Key: HBASE-10883
URL: https://issues.apache.org/jira/browse/HBASE-10883
Project: HBase
Issue Type: Improvement
Affects Versions: 0.98.1
Reporter: Andrew Purtell
Fix For: 0.99.0, 0.98.2
Currently we allow any string as visibility label or request authorization.
However as seen on HBASE-10878, we accept for authorizations strings that would
not work if provided as labels in visibility expressions. We should throw an
exception at least in cases where someone tries to define or use a label or
authorization including visibility expression operators '&', '|', '!', '(', ')'.
