IMPALA-12470 (PART-2): delete temporary file in
/tmp after class loaded
This patch fixes the bug added in the previous patch for IMPALA-12470.
It adds the prefix "file://" to the unix standard path string to
create the corresponding valid hadoop.fs.Path object. For example:
"/tmp" is converted to "file:///tmp".
Testing:
1. Deleted all the jar files in the /tmp directory.
2. Ran the local jdbc ext data sources tests:
- impala-py.test tests/query_test/test_ext_data_sources.py
- impala-py.test tests/custom_cluster/test_ext_data_sources.py
3. Upon completion of the tests successfully, Verified that there were
no .jar files in the /tmp directory.

> jdbc driver url is specified as table property 'driver.url' when creating a
> external jdbc table, like the sample below:
> {code:java}
> CREATE TABLE test_postgres (
> id INT,
> string_col STRING)
> PRODUCED BY DATA SOURCE JdbcDataSource(
> '{"database.type":"POSTGRES",
> "jdbc.url":"jdbc:postgresql://localhost:5432/functional",
> "jdbc.driver":"org.postgresql.Driver",
> "driver.url":"hdfs://localhost:20500/test-warehouse/data-sources/jdbc-driver/postgresql-jdbc.jar",
> "dbcp.username":"hiveuser",
> "dbcp.password":"password",
> "table":"alltypes"}');
> {code}
> In the initial patch, we only support to download the driver jar files from
> hdfs. We need to support different storage type, like 'file://', 's3a://',
> etc.
