---------------------------------
Summary: StreamingFileSink fails due to truncating HDFS file failure
Key: FLINK-18592
URL:
https://issues.apache.org/jira/browse/FLINK-18592 Project: Flink
Issue Type: Bug
Affects Versions: 1.10.1
Reporter: JIAN WANG
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)
{ 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.
