After HBase version 0.92, the Region server's compact process is divided into small compaction and large compaction two, depending on the size of the file to be merged, This may result in the compact consuming too much network export bandwidth when the cluster writes large amounts. This article will describe in detail the process of troubleshooting and the solution of this problem during cluster usage.
1. Finding problems

Although for layer-3 Switch, DES-3326 performance in general, support expansion slot is relatively small, but the low price is also in exchange for good cost effectiveness. DES-3326 switches are suitable for medium and small network core layer and large campus network convergence, providing Gigabit Ethernet modules can be connected to high-speed backbone network, to effectively alleviate network bottlenecks.

to know whether the expected service is available at the outlet. The network owner also wants to know:
At what rate can the network be connected?
Can this outlet provide power for VoIP phones?
Can I access the Internet?
Can I use a network printer?
DTX-NSM network service module can provide answers.
At what rate can the network be connected?
