> 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:
>
> public static <IN> StreamingFileSink<IN> build(String dir, BucketAssigner<IN,
> String> assigner, String prefix)\{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(); }
>
>
> The error is
> java.io.IOException: Problem while truncating file:
> hdfs:///business_log/hashtag/2020-06-25/.hashtag-122-37.inprogress.8e65f69c-b5ba-4466-a844-ccc0a5a93de2
> 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.
