Resource requirements for Tajo QueryMaster(=REEF Driver) #28

Open ks881115 opened 9 years ago

Following is the resource requirement of Tajo QueryMaster which would be the REEF driver in our implementation:

Memory: 512MB Disk-slots: 0 Number of Containers: 1 Request priority: Memory

There's nothing special in the requirement. But I wonder if it is possible for us to configure the resource requirement of REEF driver. Is there any way to do so?

You should be able to configure the memory via the DriverConfiguration. Take a look at:

org.apache.reef.client.DriverConfiguration: the optional parameter DRIVER_MEMORY
org.apache.reef.driver.parameters.DriverMemory

There doesn't seem to be any configuration for cores / disk-slots. The number of containers should always be one.

I think configuring Memory would be good enough. Thanks for the reply!! :)

We should be able to set #cores in Driver. @johnyangk Can you see if you can fix this easily? Thanks.
