Forward Xu commented on HADOOP-16783:
-------------------------------------
hi [~aajisaka] Sorry for replying so late, The reason there is push mode,
because our jobs are running on yarn, if you use pull mode, you must open the
port and service of each job to prometheus. This will cause a lot of waste of
resources and ports and the ports on yarn are not fixed. Using push mode can
specify a certain number of prometheus to operate and also add a layer of cache
to prometheus.
