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
java.lang.NumberFormatException: For input string: ""100""
        at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
        at java.lang.Integer.parseInt(Integer.java:569)

        at org.apache.hadoop.hbase.master.MasterRpcServices.createRpcServer(MasterRpcServices.java:435)
 

 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

  <property>
    <name>hbase.regionserver.handler.count</name>
    <value>"100"</value>
  </property>
