-----------------------------------
Summary: Failure to initialize storage plug-in results in complete
failure of drill-bit initialization
Key: DRILL-1427
URL: https://issues.apache.org/jira/browse/DRILL-1427
Project: Apache Drill
Issue Type: Bug
Components: Functions - Drill
Affects Versions: 0.5.0
Environment: Observed on CentOS 6.4 on AWS instances
Reporter: David Tucker
The storage plug-in configuration screen identifies when a plug-in fails to
initializes (eg the Hive server is down) and will leave the plug-in disabled
(or fail to creat it altogether). However, if a configured storage plug-in is
not on line when the drill-bit is launched, all attempts at interactive queries
(via sqlline or ODBC) fail to proceed. The impression left with the user is
that the drill-bit is completely off-line.
To reproduce:
1. configure Hive storage plug-in and execute simple queries
2. shut down drill-bit
3. shut down Hive server
4. re-launch the drill-bit
5. launch sqlline
... no connection will be established, no queries will be possible
