---------------------------------
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.
