Tim Armstrong commented on IMPALA-941:
--------------------------------------

[~Sethi] looks like we didn't mark it as done in help wanted. We have lots more 
newbie JIRAs if you want to make a contribution though - see 
https://issues.apache.org/jira/issues/?jql=project%20%3D%20IMPALA%20AND%20status%20in%20(Open%2C%20%22In%20Progress%22%2C%20Reopened)%20AND%20labels%20%3D%20newbie

Or if you have an area you want to learn about, reach out to 
[email protected] and we can probably find a suitable JIRA for an 
improvement (there's lots of things we want to do that we don't have enough 
contributors to do)!

> Impala Parser issue when using fully qualified table names that start with a
