--------------------------------
Labels: supportability (was: )
> Exception handling is incorrect in KerberosName.java
> ----------------------------------------------------
>
> Key: HADOOP-14389
> URL: https://issues.apache.org/jira/browse/HADOOP-14389
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Andras Bokor
> Assignee: Andras Bokor

> Attachments: HADOOP-14389.01.patch

>
> I found multiple inconsistency:
> Rule: {{RULE:\[2:$1/$2\@$3\](.\*)s/.\*/hdfs/}}
> Principal: {{nn/host.dom...@realm.tld}}
> Expected exception: {{BadStringFormat: ...3 is out of range...}}
> Actual exception: {{ArrayIndexOutOfBoundsException: 3}}
> ----
> Rule: {{RULE:\[:$1/$2\@$0](.\*)s/.\*/hdfs/}} (Missing num of components)
> Expected: {{IllegalArgumentException}}
> Actual: {{java.lang.NumberFormatException: For input string: ""}}
> ----
> Rule: {{RULE:\[2:$-1/$2\@$3\](.\*)s/.\*/hdfs/}}
> Expected {{BadStringFormat: -1 is outside of valid range...}}
> Actual: {{java.lang.NumberFormatException: For input string: ""}}
> ----
> Rule: {{RULE:\[2:$one/$2\@$3\](.\*)s/.\*/hdfs/}}
> Expected {{java.lang.NumberFormatException: For input string: "one"}}
> Acutal {{java.lang.NumberFormatException: For input string: ""}}
> ----
> In addtion:
> {code}[^\\]]{code}
> does not really make sense in {{ruleParser}}. Most probably it was needed
> because we parse the whole rule string and remove the parsed rule from
> beginning of the string: {{KerberosName#parseRules}}. This made the regex
> engine parse wrong without it.
> In addition:
> In tests some corner cases are not covered.
