Congxian Qiu updated FLINK-10794:
---------------------------------
Description:
In `StreamTask#invoke` will create CheckpointStore by
`stateBackend.createCheckpointStorage`, and create some directories.
But if the checkpoint is disabled, we could skip the creation of
checkpointStore.
IMO, the code could change to something like below
{code:java}
boolean enabledCheckpoint =
configuration.getConfiguration().getBoolean("checkpointing", false);
if (enabledCheckpoint) {
checkpointStorage =
stateBackend.createCheckpointStorage(getEnvironment().getJobID());
}
{code}
or just skip the directories creation when create CheckpointStorage
