---------------------------------------
Caused by changes introduced with FLINK-8801
> Incorrect resource time setting causes flink to fail to submit
> --------------------------------------------------------------
>
> Key: FLINK-12195
> URL: https://issues.apache.org/jira/browse/FLINK-12195
> Project: Flink
> Issue Type: Bug
> Components: Deployment / YARN, FileSystems
> Affects Versions: 1.6.3
> Reporter: tangshangwen
> Assignee: tangshangwen
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> We used Tencent COS(object storage is similar to s3) as defaultFS, and when
> we submitted the job, we ran into a YARN checking resource time mismatch that
> prevented the job from being submitted
>
> {code:java}
> 2019-04-15 14:45:47,683 DEBUG
> org.apache.hadoop.security.UserGroupInformation: PrivilegedActionException
> as:hadoop (auth:SIMPLE) cause:java.io.IOException: Resource
> cosn://xxx-xxx/user/hadoop/.flink/application_1555078596113_0014/logback.xml
> changed on src filesystem (expected 1555259286000, was 1555310742000
> {code}
> I found that flink uses the lastModified of the local file, and why is it not
> the latest time for the remote file system?
> {code:java}
> LOG.debug("Copying from {} to {}", localSrcPath, dst);
> fs.copyFromLocalFile(false, true, localSrcPath, dst);
> // Note: If we used registerLocalResource(FileSystem, Path) here, we would
> access the remote
> // file once again which has problems with eventually consistent
> read-after-write file
> // systems. Instead, we decide to preserve the modification time at the remote
> // location because this and the size of the resource will be checked by YARN
> based on
> // the values we provide to #registerLocalResource() below.
> fs.setTimes(dst, localFile.lastModified(), -1);
> // now create the resource instance
> LocalResource resource = registerLocalResource(dst, localFile.length(),
> localFile.lastModified());
> return Tuple2.of(dst, resource);{code}
> Maybe it should be
> {code:java}
> // now create the resource instance
> LocalResource resource = registerLocalResource(dst, localFile.length(),
> fs.getFileStatus(dst).getModificationTime());{code}
