Summary: Fix completer NPE
Key: ZEPPELIN-6002
URL: https://issues.apache.org/jira/browse/ZEPPELIN-6002
Project: Zeppelin
Issue Type: Bug
Reporter: Manhua Jiang
NPE occur when adding the driver specific SQL completions. Some
driver(hive-jdbc-uber-2.6.5.0-292.jar in my case) does not implement method
{{DatabaseMetaData.getDriverName()}} well and cause exception , then fail to
initialize {{{}keywordCompleter{}}}.
Since it is optional, we should avoid such driver interfere the default one,
and log it for the profession
