[HBase WebUI] Users cannot switch from the HBase WebUI to the RegionServer WebUI

Symptom

In an MRS 1.9.3 cluster, on the HBase WebUI, click any RegionServer name in the ServerName column on the Base Status tab page in the Region Servers area. The corresponding page cannot be displayed.

Procedure

  1. Log in to the node where the active OMS resides as user root and run the following command to obtain the URL of RegionServer:

    cat /opt/Bigdata/Apache-httpd*/conf/whitelist.txt |grep RegionServer

  2. Change /HMaster/ID/master-status to /RegionServer/ID/rs-status to access the RegionServer information page. In the preceding command, ID in /RegionServer/ID/rs-status is the ID corresponding to the RegionServer host name queried in 1.

    For example, if the URL of the RegionServer is /HBase/RegionServer/44, the access address is https://100.94.xxx.xxx:9022/component/HBase/RegionServer/44/rs-status.
