Hello everyone,

Command: Flink savepoint -d  reported an error。Do you know what's wrong with this command?

$ bin/flink savepoint -d file:///home/pengchenglin/flinkresult/savepoint/savepoint-ffbc58-9daf3085de9a/

------------------------------------------------------------
 The program finished with the following exception:

savepoint路径参数不对。file后面多了个一个/吧。

谢谢你的回复，我试了下，还是说缺少必填参数。
如下：
$ bin/flink savepoint -d file://home/pengchenglin/flinkresult/savepoint/savepoint-ffbc58-9daf3085de9a/

缺少了jobId 参数；
./bin/flink savepoint <jobId> [savepointDirectory]
This will trigger a savepoint for the job with ID jobId, and returns the path of the created savepoint. You need this path to restore and dispose savepoints.

你好，感谢回复，我的命令是参照官方网站，https://ci.apache.org/projects/flink/flink-docs-release-1.9/ops/state/savepoints.html#trigger-a-savepoint
$ bin/flink savepoint -d :savepointPath
这个命令是删除savepoint,你说的是触发savepoint，是没有问题的。
