That's quite weird that it tries to us the local file-system. Maybe it derives 
the FS from state.backend.fs.checckpointdir, but uses it for savepoints.dir?

What happens if you set state.backend.fs.checkpointdir also to HDFS?

Thanks Chesnay, the application will take value from "state.savepoints.dir" as 
default if set target-directory to nul. But then it trying to create the 
directory in local machine, which caused the below error because it is a HDFS 
directory. The same URL works in previous Flink 1.3.2. Is something break in 
Flink 1.5.0? Or anything we need to extra configure? Thank you.

I think you can set the target-directory to null. But I'm not sure why this 
particular request requires this, other request allow optional fields to simply 
be ommitted...

Hi all,




Seems pass in target-directory is a must now for checkpoints REST API, and the 
status will not response with save point directory anymore. I can pass in but 
the information is redundant with the same already defined in 
flink-config.yaml. May I know is there a way to retrieve the save point 
directory from flink-config.yaml in flink application? I am not able to get it 
from env.getConfig(). Thank you.

1. PATCH to /jobs/:jobid, you can specify CANCEL/STOP with the "mode" query 
parameter

2. POST to /jobs/:jobid/savepoints, with a json payload. Returns a trigger id, 
used for 3).
{
"target-directory" : {
      "type" : "string"
    },
    "cancel-job" : {
      "type" : "boolean"
    }
}

3. GET to /jobs/:jobid/savepoints/:triggerid

For #1, you need to use a PATCH request to "/jobs/:jobid"

Hi,




Regarding to Flink 1.5.0 REST API breaking change,

The REST API to cancel a job was changed.
The REST API to cancel a job with savepoint was changed.

I have few dump questions,




Any replacement for cancellation ONLY without save-point? Only found 
"/jobs/:jobid/savepoints".
For "/jobs/:jobid/savepoints", how could I form the URL with cancellation and 
with directory afterward?
http://192.168.56.151:8081/jobs/<jobid>/savepoints/cancel-job/true??
Any cancellation progress monitoring in 1.5 like previous version 1.3/1.4?
previous version: /jobs/:jobid/cancel-with-savepoint/in-progress/:requestId


Thank you.


Regards,
Yow
