Hi Till,
Actually I do send to request to the application master:
"http://storage4.test.lan:8089/proxy/application_1532081306755_0124/jobs/269608367e0f548f30d98aa4efa2211e/savepoints
<http://storage4.test.lan:8089/proxy/application_1532081306755_0124/jobs/269608367e0f548f30d98aa4efa2211e/savepoints>”
with post body
{ "target-directory" : "hdfs://flinkDsl/xxx", "cancel-job" : "true” }
If I use the following GET url, everything is OK
"http://storage4.test.lan:8089/proxy/application_1532081306755_0124/jobs/269608367e0f548f30d98aa4efa2211e/checkpoints
<http://storage4.test.lan:8089/proxy/application_1532081306755_0124/jobs/269608367e0f548f30d98aa4efa2211e/checkpoints>"
Best
