Subject [jira] [Created] (DRILL-2628) sqlline hangs and then asserts when trying to execute anything on a dead JDBC connection
Date Mon, 30 Mar 2015 23:19:53 GMT
Victoria Markman created DRILL-2628:

             Summary: sqlline hangs and then asserts when trying to execute anything on a
dead JDBC connection
                 Key: DRILL-2628
                 URL: https://issues.apache.org/jira/browse/DRILL-2628
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - JDBC
    Affects Versions: 0.8.0
            Reporter: Victoria Markman
            Assignee: Daniel Barclay (Drill)

Here is what I'm observing:

1. Start drill
2. Start sqlline
3. Run couple of queries
4. Bounce drill
5. Run in sqlline: "use dfs.temp"
It hangs and after some time throws an exception:

0: jdbc:drill:schema=dfs> use dfs.joins_views;

Comment on a dead JDBC connection is a speculation on my part. I don't know what is actually
