Chesnay Schepler updated FLINK-22069: ------------------------------------- Description: We should check for log pollution and confusing log lines before the release. Below are some lines I stumbled over while using Flink during testing. ----------------------------- These lines show up on any execution of a local job and make me think I forgot to configure something I probably should have, wondering whether this might cause problems later? These have been in Flink for a few releases now, might be worth rephrasing, though. {code} 2021-03-30 17:57:22,483 INFO org.apache.flink.runtime.taskexecutor.TaskExecutorResourceUtils [] - The configuration option taskmanager.cpu.cores required for local execution is not set, setting it to the maximal possible value. 2021-03-30 17:57:22,483 INFO org.apache.flink.runtime.taskexecutor.TaskExecutorResourceUtils [] - The configuration option taskmanager.memory.task.heap.size required for local execution is not set, setting it to the maximal possible value. 2021-03-30 17:57:22,483 INFO org.apache.flink.runtime.taskexecutor.TaskExecutorResourceUtils [] - The configuration option taskmanager.memory.task.off-heap.size required for local execution is not set, setting it to the maximal possible value. 2021-03-30 17:57:22,483 INFO org.apache.flink.runtime.taskexecutor.TaskExecutorResourceUtils [] - The configuration option taskmanager.memory.network.min required for local execution is not set, setting it to its default value 64 mb. 2021-03-30 17:57:22,483 INFO org.apache.flink.runtime.taskexecutor.TaskExecutorResourceUtils [] - The configuration option taskmanager.memory.network.max required for local execution is not set, setting it to its default value 64 mb. 2021-03-30 17:57:22,483 INFO org.apache.flink.runtime.taskexecutor.TaskExecutorResourceUtils [] - The configuration option taskmanager.memory.managed.size required for local execution is not set, setting it to its default value 128 mb. {code} -------------------------------- When using {{DataStream.collect()}} we always have an excpetion in the log for the first fetch attempt, before the JM is ready.
