Hi， I got the same exception when running in flink cluster. The settings is below:
flink version: 1.5.4 flink-conf.yaml: jobmanager.heap.mb: 102400 taskmanager.heap.mb: 102400 taskmanager.numberOfTaskSlots: 40 parallelism.default: 40 I have 5 task manager. My code just read hbase table data and write to another table. The size of data about 1TB. Thanks!
