B bds-config.json Configuration Example
This example demonstrates some of the available configuration parameters and values.
The group hadoop_ids
is new in Oracle Big Data SQL 4.1. The values
that this example shows for the parameters in this group are the implicit default
values, which do not need to be specified in the configuration file. If you want to
set non-default values, then include the hadoop_ids
parameters in
the configuration file.
