hbase.regionserver.msginterval 1000 Interval between messages from the RegionServer to HMaster in milliseconds. Default is 15. Set this value low if you want unit tests to be responsive. hbase.client.pause 5000 General client pause value. Used mostly as value to wait before running a retry of a failed get, region lookup, etc. hbase.master.meta.thread.rescanfrequency 10000 How long the HMaster sleeps (in milliseconds) between scans of the root and meta tables. hbase.server.thread.wakefrequency 1000 Time to sleep in between searches for work (in milliseconds). Used as sleep interval by service threads such as META scanner and log roller. hbase.regionserver.handler.count 5 Count of RPC Server instances spun up on RegionServers Same property is used by the HMaster for count of master handlers. Default is 10. hbase.master.lease.period 6000 Length of time the master will wait before timing out a region server lease. Since region servers report in every second (see above), this value has been reduced so that the master will notice a dead region server sooner. The default is 30 seconds. hbase.master.lease.thread.wakefrequency 3000 The interval between checks for expired region server leases. This value has been reduced due to the other reduced values above so that the master will notice a dead region server sooner. The default is 15 seconds. hbase.rootdir /hbase location of HBase instance in dfs
