Re: Server side error: Cannot find required BLOB at /tmp/blobStore


Hi.

From my presentation on Flink forward you can validate this
We used EMR on Amazon’s Linux AMI
We didn't change the default blob server location (/tmp)
Default a cron job cleaning up in /tmp
Solution change blob server location with blob.storage.directory

/tmp/blobStore 
Is it the path  for checkpoints/savepoints  storage ?

Hi,

 

My Flink application which reads from Kafka and writes to HDFS is failing repeatedly with below exception:

 

Caused by: java.io.IOException: Server side error: Cannot find required BLOB at /tmp/blobStore-**********

 

Can someone please help me on, what could be the root cause of this issue?  I am not able to trace logs also.

 

Also, FYI, our FLINK cluster(4nodes) is setup on our Hadoop YARN cluster.

 

Thanks a lot.
