Hi Till,
I am using flink 1.7.
This is my observation.
a) I first trigger a savepoint. this is stored on my Google cloud storage.
b) When i invoke the rescale HTTP API, i get the error telling savepoints
dir is not configured. But post triggering a), i could verify the savepoint
directory present in GCS in the mentioned path.
Below is the snapshot of my deployment file.
Environment:
JOB_MANAGER_RPC_ADDRESS: svc-flink-jobmanager-gcs
HIGH_AVAILABILITY: zookeeper
HIGH_AVAILABILITY_ZOOKEEPER: zookeeper-dev-1:2181
HIGH_AVAILABILITY_ZOOKEEPER_PATH_ROOT: /flink-gcs-chk
HIGH_AVAILABILITY_CLUSTER_ID: fs.default_ns
HIGH_AVAILABILITY_STORAGEDIR:
gs://xxxxx/flink/flink-gcs/checkpoints
HIGH_AVAILABILITY_JOBMANAGER_PORT: 6123
STATE_CHECKPOINTS_DIR:
gs://xxxxx/flink/flink-gcs/flink-checkpoints
STATE_SAVEPOINTS_DIR:
gs://xxxxx/flink/flink-gcs/flink-savepoints
Response to my Savepoints REST API is as below:
{
"status": {
"id": "COMPLETED"
},
"operation": {
"location":
"gs://xxxxx/flink/flink-gcs/flink-savepoints/savepoint-d02217-ec0aced1fe9c"
}
}
So why does the job doesnt recognize this savepoint directory ? Also,
during this operation, i could see the Checkpoints directory for this job
gets deleted. Post which, no checkpoints are happening. any thoughts here
would really help us in progressing.
Thanks,
