HBase集群中RegionServer崩溃后的快速恢复措施探索

The HBase cluster explore measures to quickly restore RegionServer after the collapse of the RegionServer

主要介绍了HBase RegionServer与Zookeeper间的交互过程,阐述RegionServer崩溃后的恢复机制,并在此基础上提出了几点优化的恢复措施。优化后的恢复措施大大缩短了RegionServer崩溃后的故障恢复时间和业务中断时间,从而提高了HBase集群的稳定性和可靠性。

This paper mainly introduces the interactive process between Zookeeper and HBase RegionServer, the recovery mechanism after the collapse of the RegionServer, and puts forward some optimization restoration measures. The recovery measures after optimization greatly reduces the RegionServer fault recovery time and the service interruption time after the collapse , thereby improving the stability and reliability of HBase clusters.
