Hi, I’ve got two more questions on different topic…
First one : Is there a way to monitor the buffers status. In order to find bottleneck in our application we though it could be usefull to be able to have a look at the different exchange buffers’ status. To know if they are full (or as an example if a mapper had to wait before being able to push it’s data into the buffer). That way we can know where the bottleneck is. Second one : On type of resources on yarn is vCPU. In flink 0.8 there was a “-tmc” argument that allowed to specify the number of vCPU per task manager. We cannot find it anymore. Was it removed ? Is there another way to set the number of vCPU. Or did it became useless ? Thanks in advance. Gwen’
