Method | Description |
---|---|
List<String> parseInitFile(String initFile) |
Parses initial SQL file skipping comments that starts with #
or -- . |
Method | Description |
---|---|

JdbcConnectionParams parseURL(String uri) |
Parse JDBC connection URL The new format of the URL is:
where
the optional sess , conf , and var
lists are semicolon separated = pairs. For utilizing dynamic
service discovery with HiveServer2, multiple comma-separated host:port pairs can be
specified as shown above. The JDBC driver resolves the list of URIs and picks a
specific server instance to connect to. Currently, dynamic service discovery using
ZooKeeper is supported, in which case the host:port pairs represent a ZooKeeper
ensemble. As before, if the host/port is not specified, it the driver runs an
embedded Hive:
http://server:10001/hs2 , with specified
basicAuth credentials and initial database:

Security-related API changes
The following properties are removed from the default hive-site.xml
configuration on a secured cluster:
Property | Value |
---|---|
hive.server2.webui.keystore.path |
/opt/mapr/conf/ssl_keystore . |
hive.server2.webui.keystore.password |
Default keystore password . |
The following property is added to the default hive-site.xml
configuration
on a secured cluster:
Method | Description |
---|---|
hive.server2.use.SSL true |
true |
Since the HiveServer2 server is configured to use SSL encryption by default starting from
Hive-2.3 EEP-6.0.0, add ssl=true
;
to a JDBC connection string when PAM or MAPR-SASL authentication is used.
For example:
Old JDBC connection string with PAM authentication:
beeline> !connect jdbc:hive2://<host>:10000/default;
New JDBC connection string with PAM authentication:
beeline> !connect jdbc:hive2://<host>:10000/default;ssl=true;
NOTE
All API functionality changes are compatible with previous versions.
