lmccay opened a new pull request #241: KNOX-1742 - Simple SQL Client in 
KnoxShell for access to JDBC sources
URL: https://github.com/apache/knox/pull/241
 
 
   (It is very **important** that you created an Apache Knox JIRA for this 
change and that the PR title/commit message includes the Apache Knox JIRA ID!)
   
   ## What changes were proposed in this pull request?
   Adding a simple SQL client/shell to KnoxShell for accessing JDBC data 
sources such as HiveServer2 and others. Rather than providing connection 
details on the command line for the data source, this shell leverages the 
DataSource persistence introduced in KNOX-2128.
   
   Enter the SQL client, list datasources, select datasources and execute SQL 
query:
