Hi Huiming, Have you recovered from this bad situation? When an RS is down, HBase needs to take a while to identify the bad RS and then move its data to another RS. How long this will take will depends on several factors. The following post is discussing it.
https://stackoverflow.com/questions/36579219/how-long-hbase-need-to-take-for-recovering-one-crashed-regionserver The port may be different if RS found the default port is not available. So you may need double check HBase's configuration. Please share with us if you have further information.
