trying to execute anything on a dead JDBC connection
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:
{code}
0: jdbc:drill:schema=dfs> use dfs.joins_views;
java.lang.AssertionError

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