Strange pauses with HDFS FileOutput operator
Hi, all – I’m seeing strange behavior in my app. I’m observing periodic dropouts of “tuples processed” as shown in the picture below. I theorized that this has to do with the flushSize for the AbstractFileOutputOperator I’m extending but that doesn’t seem to be the case. The other option is that this has to do with the compression stream I’ve added, has anyone seen something similar before?

Hi Ilya,
It will be helpful if you provide a screenshot of the DAG.
Thank you,
