Subject RE: Problems with RollingSink

Hi Kostas,

Thanks for your reply.

The problem is at the initialization of the job.  The reason was that I was using the same
HDFS path as sink for 3 different streams, which is something that I would like. I can fix
it by using different paths
for each stream.

Maybe there is a way to achieve this in a different manner by joining the streams somehow
before sinking… maybe through Kafka?

Kind Regards,

Hi Diego,

The message shows that two tasks are trying to touch concurrently the same file.

This message is thrown upon recovery after a failure, or at the initialization of the job?
Could you please check the logs for other exceptions before this?

Can this be related to this issue?

Hi colleagues,

I am experiencing problems when trying to write events from a stream to HDFS. I get the following

failed to create file /user/biguardian/events/2016-11-28--15/flinkpart-0-0.text for DFSClient_NONMAPREDUCE_1634980080_43
for client because current leaseholder is trying to recreate file.

My Flink version is 1.1.3 and I am running it directly from a JAR (not in YARN) with java

Do you know the reason of this error?

Kind regards,
