                 Key: CHUKWA-108
                 URL: https://issues.apache.org/jira/browse/CHUKWA-108
             Project: Hadoop Chukwa
          Issue Type: Improvement
          Components: Data Processors
            Reporter: Eric Yang


To prevent SQL Injection attacks, you should use prepared statements. There are 
many places where the SQL query is executed and in atleast a couple of places 
the input parameter from the user is used in the query. (metric in 
web/hicc/jsp/single-series-chart-javascript.jsp") though in many places the 
parameters in the select statement do not seem to come from the user input.

Please use prepared statement consistently to prevent sql injection attacks.
