-------------------------------------

             Summary: Odd behaviors of TableName for empty namespace
                 Key: HBASE-11064
                 URL: https://issues.apache.org/jira/browse/HBASE-11064
             Project: HBase
          Issue Type: Bug
            Reporter: Hiroshi Ikeda
            Priority: Trivial


In the class TableName,
{code}
public static byte [] isLegalFullyQualifiedTableName(final byte[] tableName) {
...
int namespaceDelimIndex = ...
if (namespaceDelimIndex == 0 || namespaceDelimIndex == -1){
  isLegalTableQualifierName(tableName);
} else {
...
{code}

That means, for example, giving ":a" as the argument throws an exception which says invalid qualifier, instead of invalid namespace.

Also, TableName.valueOf(String) and valueOf(byte[]) can create an instance with empty namespace, which is inconsistent.
