   This seems like a weird failed test. I can ran it successfully in my local env with command:
   `mvn test -Dtest.output.overwrite -DskipSparkTests -Dtest=TestMiniLlapLocalCliDriver -Dqfile=dataconnector_mysql_bit_datatype.q`
   
   But in the pr integration test it failed with error:
   `fname=dataconnector_mysql_bit_datatype.q
   See ./ql/target/tmp/log/hive.log or ./itests/qtest/target/tmp/log/hive.log, or check ./ql/target/surefire-reports or ./itests/qtest/target/surefire-reports/ for specific test cases logs.
    org.apache.hadoop.hive.ql.parse.SemanticException: Unable to fetch table work_calendar. Error retrieving remote table:java.sql.SQLNonTransientConnectionException: (conn=4) Connection is closed

    at org.apache.hadoop.hive.ql.ddl.table.create.show.ShowCreateTableAnalyzer.analyzeInternal(ShowCreateTableAnalyzer.java:53)`
   
   I think the integration test env may has something wrong. It may be a database driver compatibility problem or something others.  
   Do you have any suggestions ? @nrg4878 @zabetak @kgyrtkirk
