Subject [jira] [Commented] (HADOOP-15234) NPE when initializing KMSWebApp
Date Fri, 02 Mar 2018 21:59:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16384216#comment-16384216
] 

Xiao Chen commented on HADOOP-15234:
------------------------------------

Thanks for the patch [~zhenyi].

Some comments:
 * We can actually use preconditions {{checkArgument}} method to check the variable and provide
the exception message.
 * Suggest to use {{HADOOP_SECURITY_KEY_PROVIDER_PATH}} from {{CommonConfigurationKeysPublic}}
instead of hard code.
 * Idea of testing is good. Suggest to instead of using {{isExitSystem}}, use a more self-explaining
variable name like {{rethrowExceptionForTesting}}

> During KMS startup, if the {{keyProvider}} is null, it will NPE inside KeyProviderExtension.
> {noformat}
> java.lang.NullPointerException
> 	at org.apache.hadoop.crypto.key.KeyProviderExtension.<init>(KeyProviderExtension.java:43)
> 	at org.apache.hadoop.crypto.key.CachingKeyProvider.<init>(CachingKeyProvider.java:93)

> We're investigating the exact scenario that could lead to this, but the NPE and log around
it can be improved.
