Issue pyodbc and to_sql HIVE
#### Code Sample, a copy-pastable example if possible

engine_clus= pyodbc.connect(connection_string, autocommit=True)

df.to_sql("table", con=engine_clus, if_exists='append', index = False, schema = 'schema')

#### Problem description
We need to load in HIVE a dataframe which contains information from a source cluster. 
Using pyodbc we can create, drop and select but we can't do inserts because of the following error:
DatabaseError: Execution failed on sql 'SELECT name FROM sqlite_master WHERE type='table' AND name=?;': ('HY000', '[HY000] [Microsoft][Hardy] (79) Failed to reconnect to server. (79) (SQLPrepare)')

#### Expected Output
We expected to be able to insert information from a dataframe.
