Lukas Majercak updated HADOOP-15951:
------------------------------------
Description:
Currently, LdapGroupsMapping.doGetGroups catches a very generic NamingException
and retries no matter what the actual root cause is. In a lot of cases, for
example when the actual exception is NameNotFoundException, retrying will be
pointless.
The proposal is to distinguish between retryable (e.g. CommunicationException)
and non-retryable LDAP exceptions (such as InvalidAttributesException).
