[jira] [Created] (FLINK-3803) Checkpoint Stats Tracker Reads from
Wrong Configuration
Aljoscha Krettek created FLINK-3803:
---------------------------------------
Summary: Checkpoint Stats Tracker Reads from Wrong Configuration
Key: FLINK-3803
URL: https://issues.apache.org/jira/browse/FLINK-3803
Project: Flink
Issue Type: Bug
Components: Streaming
Affects Versions: 1.0.0
Reporter: Aljoscha Krettek
In {{ExecutionGraph.java}} when configuring the checkpoint stats tracker the config values are read from the {{jobConfiguration}}:
{code}
boolean isStatsDisabled = jobConfiguration.getBoolean(
ConfigConstants.JOB_MANAGER_WEB_CHECKPOINTS_DISABLE,
ConfigConstants.DEFAULT_JOB_MANAGER_WEB_CHECKPOINTS_DISABLE);
if (isStatsDisabled) {
checkpointStatsTracker = new DisabledCheckpointStatsTracker();
}
else {
int historySize = jobConfiguration.getInteger(
ConfigConstants.JOB_MANAGER_WEB_CHECKPOINTS_HISTORY_SIZE,
ConfigConstants.DEFAULT_JOB_MANAGER_WEB_CHECKPOINTS_HISTORY_SIZE);
checkpointStatsTracker = new SimpleCheckpointStatsTracker(historySize, tasksToWaitFor);
}
{code}
The settings are only available in the Flink Configuration, however. Right now, the {{ExecutionGraph}} has no access to the Flink Configuration.
I see three solutions:
- pass the Flink Configuration to the {{ExecutionGraph}}
- pass just the two required settings to the {{ExecutionGraph}}
- Introduce a new {{ExecutionGraphSettings}} that contains settings only for the {{ExecutionGraph}} in order to clean up things a bit
