             Summary: Fix graphviz dag generation for Hive
                 Key: TEZ-876
                 URL: https://issues.apache.org/jira/browse/TEZ-876
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Hitesh Shah


Hive uses ":" and "-" in the dag name which are special chars for dot. Need to 
be escaped or replaced. 

Also, would be useful to log a message in the AM logs with the dot file 
location.
