Configuring JDBC for Impala
Download and configure the JDBC driver to access Impala from a Java program that you write, or a Business Intelligence or similar tool that uses JDBC to communicate with database products.
The following are the default ports that Impala server accepts JDBC connections through:
Protocol | Default Port | Flag to Specify an Alternate Port |
HTTP | 28000 | ‑‑hs2_http_port
|
Binary TCP | 21050 | ‑‑hs2_port
|
Make sure the port for the protocol you are using is available for communication with clients, for example, that it is not blocked by firewall software.
If your JDBC client software connects to a different port, specify that alternative port
number with the flag in the above table when starting the impalad
.
