Hi Benjamin, i think doing
{noformat}
try {
plan = parser.Parse();
} catch (ParseException e) {
log.error(e.getMessage());
log.debug(e);
}
{noformat}
is fine. But not in LogicalPlanBuilder, better somewhere in Grunt.
I think the duplicate logging could be avoided with something like:
{noformat}
if(log.isDebugEnabled()){
log.error(e.getMessage(), e);
}{
log.error(e.getMessage());
}
{noformat}
