Yun Gao commented on FLINK-30412: --------------------------------- Hi [~xiaodao] sorry for the late reply, may I have a double check on the version you are using? Since From the stack, it seems it is still trying to create a JobManagerRunner object, but JobManagerRunner has been changed to be an interface since 1.10: https://issues.apache.org/jira/browse/FLINK-14259 Since https://issues.apache.org/jira/browse/FLINK-23180 is merged in 1.15, if you are using a version earlier than 1.15.0 I reckon it might be fixed by upgrading. > create many checkpoint empty dir when job not enable checkpoint > --------------------------------------------------------------- > > Key: FLINK-30412 > URL: https://issues.apache.org/jira/browse/FLINK-30412 > Project: Flink > Issue Type: Improvement > Components: API / DataStream > Affects Versions: 1.12.7, 1.13.6, 1.15.2 > Reporter: xiaodao > Priority: Major > Attachments: image-2022-12-23-09-24-58-584.png > > > when we submit job to flink session cluster , after a long time, we find it > create too much > empty checkpoint dir,and it over hdfs max node limit ; > i found StreamingJobGraphGenerator set snapshot whennever the job is open > checkpoint; > jobGraph.setSnapshotSettings(settings) > {code:java} > private void configureCheckpointing() > CheckpointConfig cfg = streamGraph.getCheckpointConfig(); long interval = > cfg.getCheckpointInterval(); if (interval < MINIMAL_CHECKPOINT_TIME) { // > interval of max value means disable periodic checkpoint interval = > Long.MAX_VALUE; } > {code} -- This message was sent by Atlassian Jira (v8.20.10#820010)
