More details about the error stack please refer to the [original

[~ALVINWJ] I think your analysis makes sense that we should have tried to
recover lease after the lease timeout passed but file still not closed in
{{HadoopRecoverableFsDataOutputStream#waitUntilLeaseIsRevoked}}, and we could
reuse the [RecoverLeaseFSUtils tool in
HBase|https://github.com/apache/hbase/blob/a9a1b9524daa9e33541c655620b9c07d5a93d533/hbase-asyncfs/src/main/java/org/apache/hadoop/hbase/util/RecoverLeaseFSUtils.java]
to implement this.
Since you've done a good job of analyze the problem, would you like to submit a
PR to fix this? Or just let us know if you prefer someone else to do the task.
Thanks.

> Key: FLINK-18592
> URL: https://issues.apache.org/jira/browse/FLINK-18592
> Project: Flink
> Issue Type: Bug
> Components: Connectors / FileSystem
> Affects Versions: 1.10.1
> Reporter: JIAN WANG
> Priority: Major
>
> I meet the issue on flink-1.10.1. I use flink on YARN(3.0.0-cdh6.3.2) with
> StreamingFileSink.
> code part like this:
> {code}
> public static <IN> StreamingFileSink<IN> build(String dir,
> BucketAssigner<IN, String> assigner, String prefix) {
> return StreamingFileSink.forRowFormat(new Path(dir), new
> SimpleStringEncoder<IN>())
> .withRollingPolicy(
> DefaultRollingPolicy
> .builder()
>
> .withRolloverInterval(TimeUnit.HOURS.toMillis(2))
>
> .withInactivityInterval(TimeUnit.MINUTES.toMillis(10))
> .withMaxPartSize(1024L * 1024L * 1024L
> * 50) // Max 50GB
> .build())
> .withBucketAssigner(assigner)
>
> .withOutputFileConfig(OutputFileConfig.builder().withPartPrefix(prefix).build())
> .build();
> }
> {code}
> The error is
> {noformat}
> java.io.IOException:
> Problem while truncating file:
> hdfs:///business_log/hashtag/2020-06-25/.hashtag-122-37.inprogress.8e65f69c-b5ba-4466-a844-ccc0a5a93de2
> {noformat}
> Due to this issue, it can not restart from the latest checkpoint and
> savepoint.
> Currently, my workaround is that we keep latest 3 checkpoint, and if it
> fails, I manually restart from penult checkpoint.
