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

             Summary: Provide flag to disable uppercase characters in column/table names
                 Key: KUDU-1996
                 URL: https://issues.apache.org/jira/browse/KUDU-1996
             Project: Kudu
          Issue Type: Improvement
          Components: master
    Affects Versions: 1.3.0
            Reporter: Dan Burkert


The rest of the Hadoop ecosystem (Hive, SparkSQL, Impala) can't handle uppercase or non-ascii characters in table and column names. Users who create these tables through the Kudu client may not recognize that the table won't be addressable by SparkSQL and Impala.  Removing support would be a breaking change, but we can provide a flag on the master that will reject any CREATE/ALTER statements which introduce non-conforming names.

Additionally, we should fix the CREATE EXTERNAL TABLE Impala logic to display an error when the column/table name doesn't conform.
