> Precondition:
> hbase.balancer.tablesOnMaster = true
> hbase.balancer.tablesOnMaster.systemTablesOnly = true
> In case of master-rs collocation HBASE_ZNODE_FILE is overwritten by
> regionserver process in HRegionServer#handleReportForDutyResponse() here is
> how it looks on master server:
> [hadoop@master-node data]$ cat hbase-hadoop-master.znode
> /hbase/rs/master-node,16000,1578371505720
> When ZNodeClearer#clear(), the rsZNode is also splicing with the contents of
> the file, causing an exception：
> java.lang.IllegalArgumentException: Invalid path string
> "/hbase/rs//hbase/rs/master-node,16000,1578371503003" caused by empty node
