Andras Bokor created HADOOP-14389:
-------------------------------------
Summary: 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
I found multiple inconsistency:
Rule: {{RULE:\[2:$1/$2\@$3\](.\*)s/.\*/hdfs/}}
Principal: {{nn/[email protected]}}
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.
