ERROR [main] regionserver.HRegionServer: Failed construction RegionServer

今天重启hbase的hmaster，发现起不来hmaster

去hbase的日志里面看

 看到如下问题

2022-01-23 10:46:24,023 ERROR [main] regionserver.HRegionServer: Failed construction RegionServer

 问题hbase-site.xml有人多加了个配置，这个值带引号导致的这个问题，去掉引号，重新启动hmaster即可解决

 
    hbase.regionserver.handler.count
    "100"
