Re: How are samza.container.id generated in yarn?

[Yi Pan]

Hi, Debraj,

In YARN environment, Samza uses YARN generated containerIds as
environmental variables to set each container process's samza.container.id.
i.e. when containers are requested by Samza AM process in YARN, YARN RM
will reply with a set of allocated container objects, which is of class
org.apache.hadoop.yarn.api.records.Container. That's the resource class to
uniquely identify a container in YARN and Container#getId().toString() is
the container ID string we set to samza.container.id.

Best,

-Yi
