Machine 128G memory， rss Xmx 75G, -XX:MaxDirectMemorySize=20G.

Now, rss.server.shuffleBufferManager.trigger.flush.interval is default value and flush check thread is close, and we want to set it to 180 and enable flush check.

Now the huge partition is default value 20G, and it is bigger for me, I want to adjust to 8G according to the log: (Make it flush early)
