>
> Key: HADOOP-19308
> URL: https://issues.apache.org/jira/browse/HADOOP-19308
> Project: Hadoop Common
> Issue Type: Bug
> Components: common, security
> Affects Versions: 3.4.0, 3.3.6, 3.4.1, 3.4.2
> Environment: RHEL9
> Reporter: Abhey Rana
> Priority: Critical
> Attachments: stacktrace.txt
>
> Original Estimate: 96h
> Remaining Estimate: 96h
>
> FastSaslClientFactory is instantiated in both SaslRpcClient and SaslParticipant as new FastSaslClientFactory(null)
> In its constructor FastSaslClientFactory loads all the SaslFactories using Sasl.getSaslClientFactories();
> Then it iterates through all the loaded factories and calls getMechanismNames method.
> The null argument sent in the constructor is sent to the getMechanismNames call.
> In some-cases, a loaded factory might not handle this null argument and might throw a NPE.
> This can cause the entire FastSaslClientFactory to not instantiate leading to failure while instantiation of SaslRpcClient.
> Code Pointer - [https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/FastSaslClientFactory.java#L43]
