Subject [jira] [Commented] (DRILL-2932) Errors reported through System.out.println, and text not in thrown SQLException message
Date Sat, 02 May 2015 04:22:09 GMT

    [ https://issues.apache.org/jira/browse/DRILL-2932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14524563#comment-14524563
] 

Daniel Barclay (Drill) commented on DRILL-2932:
-----------------------------------------------

Additionally, the text intended to reach the user is not copied into the message of the SQLException
that is thrown to the JDBC client.

> There is a call to System.out.println(...) in DrillResultSetImpl.ResultListener.submissionFailed(...):
>   System.out.println("Query failed: " + ex.getMessage());
> (That submissionFailed(...) is part of the implementation of Statement.execute...(...)
methods and ResultSet.)
> In SQLLine, this causes the exception message, which currently doesn't show up otherwise
in SQLLine, to show up when running SQLLine interactively.
> However, writing that to System.out. is completely inappropriate. 
> JDBC specifies that implementations throw SQLExceptions to report errors\--implementations
should not be unilaterally be deciding to write to stdout\--or stderr.
