---------------------------------------
Summary: BucketingSink does not sync file length in case of cancel
Key: FLINK-6427
URL: https://issues.apache.org/jira/browse/FLINK-6427
Project: Flink
Issue Type: Bug
Components: Streaming Connectors
Affects Versions: 1.2.1, 1.3.0
Reporter: Aljoscha Krettek
Assignee: Aljoscha Krettek
This is from a discussion on the user mailing lists:
https://lists.apache.org/thread.html/917dbbbd7c8f48b33e7b470fa9ed382df61cf43cb5deb46becebf4b5@%3Cuser.flink.apache.org%3E
A possible solution is to add this to {{StreamWriterBase.hflushOrSync()}}:
{code}
if (os.getWrappedStream() instanceof DFSOutputStream) {
((DFSOutputStream)
os.getWrappedStream()).hsync(EnumSet.of(HdfsDataOutputStream.SyncFlag.UPDATE_LENGTH));
}
{code}
