Hi
   这个你可以尝试把这个信息记录到哪里，或者在启动的时候从这个 jobId 的目录下去查找所有的 chk-xxx 然后选择一个合适的 目录进行恢复
Best,

刚钉钉群里建议我把路径指到jobId/chk-xx目录，这样就可以恢复了。

但是如果这样，这个xx随着checkpoint的变化而变化，这样怎么做到自动提交job?

谢谢， 我把这个folder 设置为一个755就可以了。

但现在我遇到一个问题，我目前的环境是用docker 创建了一个jobmanager, 二个taskmanager,
这三个container都map到了主机上的一个地址，
用于放checkpoints/savepoints，理论上这三个container都可以访问得到。

但尝试用这个命令恢复state启动job时报以下错误，
/opt/flink/bin/flink run -d -s /opt/flink/savepoints -c
com.coinflex.flink.ohlc.kafka.OrderTickCandleView
/home/service-ohlc-*-SNAPSHOT.jar

job启动不了。

Hi
从报错来看是无法在 "/opt/flink/savepoints" 这个路径下创建目录，这个错误下面应该应该一些异常信息，可以看下具体是啥原因。
另外，使用本地路径存储 checkpoint/savepoint 的话，那么恢复的时候，需要确保该文件能被新的 JM/TM 所访问到

Best,
Congxian

flink state.savepoints.dir 目录配置问题

2020-10-26 文章 marble.zh...@coinflex.com.INVALID 
你好， 
我在flink jobmanager里的flink-conf.yaml添加了以加三个个关的state配置参数，
state.backend: filesystem
state.checkpoints.dir: file:///opt/flink/savepoints
state.savepoints.dir: file:///opt/flink/savepoints 


但在做./flink savepoint 时还是报以下的错， 

Caused by: java.io.IOException: Failed to create savepoint directory at
file:/opt/flink/savepoints
at
org.apache.flink.runtime.state.filesystem.AbstractFsCheckpointStorage.initializeLocationForSavepoint(AbstractFsCheckpointStorage.java:167)
at
org.apache.flink.runtime.checkpoint.CheckpointCoordinator.lambda$initializeCheckpoint$8(CheckpointCoordinator.java:633)
... 8 more


我需要做哪些调整，是只能支持hdfs吗？  多谢， 急。
