For FLINK-6912:There are three implementations of RichFunction that actually use the Configuration parameter in RichFunction#open: 1. ContinuousFileMonitoringFunction#open: It uses the configuration to configure the FileInputFormat. [1] 2. OutputFormatSinkFunction#open: It uses the configuration to configure the OutputFormat. [2] 3. InputFormatSourceFunction#open: It uses the configuration to configure the InputFormat. [3]
And none of them should have any effect since the configuration is empty. See org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator#open.
