URL: https://issues.apache.org/jira/browse/HADOOP-19010
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 3.3.0
Reporter: Anika Kelhanka
*Description*: Hadoop's credential check throws {{NullPointerException}} when
alias not found.
{code:bash}
hadoop credential check "fs.gs.proxy.username" -provider
"jceks://file/usr/lib/hive/conf/hive.jceks" {code}
Checking aliases for CredentialProvider:
jceks://file/usr/lib/hive/conf/hive.jceks
Enter alias password:
java.lang.NullPointerException

org.apache.hadoop.security.alias.CredentialShell$CheckCommand.execute(CredentialShell.java:369)
at org.apache.hadoop.tools.CommandShell.run(CommandShell.java:73)
at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:82)
at
org.apache.hadoop.security.alias.CredentialShell.main(CredentialShell.java:529)}}
*Expected Behavior:* The check command should display *check failed message*
when alias not found similar to what it throws for incorrect alias value i.e
following failure message:
{{Password match failed for javax.jdo.option.ConnectionPassword.}}
