-----------------------------------------
Summary: NPE in SaslRpcServer
Key: HADOOP-12567
URL: https://issues.apache.org/jira/browse/HADOOP-12567
Project: Hadoop Common
Issue Type: Task
Reporter: Sergey Shelukhin
{noformat}
if (LOG.isDebugEnabled()) {
String username =
getIdentifier(authzid, secretManager).getUser().getUserName();
LOG.debug("SASL server DIGEST-MD5 callback: setting "
+ "canonicalized client ID: " + username);
}
{noformat}
Looking at identifier implementations, e.g. AbstractDelegationTokenIdentifier
(and others), I can see that getUser method can return null. If debug logging
is enabled, this NPEs.
If getUser is not expected to return NULL, it should either be checked and
erred upon better here, or the error should be allowed to happen where it would
otherwise happen, not in some debug log statement.
