## What is the purpose of the change Before the change, everytime the REST UI tried to access the checkpointing statistics, an ERROR message was logged. When using a BATCH job, this leads to log files looking like this: ``` 2020-11-13 15:27:38,785 ERROR org.apache.flink.runtime.rest.handler.job.checkpoints.CheckpointConfigHandler [] - Exception occurred in REST handler: Checkpointing is not enabled for this job (6df1c639d1904f8b7a54cf6a649ab567). 2020-11-13 15:27:38,788 ERROR org.apache.flink.runtime.rest.handler.job.checkpoints.CheckpointConfigHandler [] - Exception occurred in REST handler: Checkpointing is not enabled for this job (6df1c639d1904f8b7a54cf6a649ab567). 2020-11-13 15:27:38,788 ERROR org.apache.flink.runtime.rest.handler.job.checkpoints.CheckpointingStatisticsHandler [] - Exception occurred in REST handler: Checkpointing has not been enabled. 2020-11-13 15:27:38,793 ERROR org.apache.flink.runtime.rest.handler.job.checkpoints.CheckpointingStatisticsHandler [] - Exception occurred in REST handler: Checkpointing has not been enabled. 2020-11-13 15:27:38,793 ERROR org.apache.flink.runtime.rest.handler.job.checkpoints.CheckpointConfigHandler [] - Exception occurred in REST handler: Checkpointing is not enabled for this job (6df1c639d1904f8b7a54cf6a649ab567). 2020-11-13 15:27:38,797 ERROR org.apache.flink.runtime.rest.handler.job.checkpoints.CheckpointingStatisticsHandler [] - Exception occurred in REST handler: Checkpointing has not been enabled. 2020-11-13 15:27:38,797 ERROR org.apache.flink.runtime.rest.handler.job.checkpoints.CheckpointConfigHandler [] - Exception occurred in REST handler: Checkpointing is not enabled for this job (6df1c639d1904f8b7a54cf6a649ab567). 2020-11-13 15:27:38,802 ERROR org.apache.flink.runtime.rest.handler.job.checkpoints.CheckpointingStatisticsHandler [] - Exception occurred in REST handler: Checkpointing has not been enabled. ``` With this change, these log messages are suppressed. ## Brief change log - Introduce a "log exception" flag to `RestHandlerException`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
