hbase.master 0.0.0.0:60000 The host and port that the HBase master runs at. TODO: Support 'local' (All running in single context). hbase.regionserver 0.0.0.0:60010 The host and port a HBase region server runs at. hbase.regionserver.class org.apache.hadoop.hbase.HRegionInterface An interface that is assignable to HRegionInterface. Used in HClient for opening proxy to remote region server. hbase.rootdir ${hadoop.tmp.dir}/hbase The directory shared by region servers. hbase.client.pause 30000 General client pause value. Used mostly as value to wait before running a retry of a failed get, region lookup, etc. hbase.client.retries.number 5 Maximum retries. Used as maximum for all retryable operations such as fetching of the root region from root region server, getting a cell's value, starting a row update, etc. Default: 5. hbase.master.meta.thread.rescanfrequency 60000 How long the HMaster sleeps (in milliseconds) between scans of the root and meta tables. hbase.master.lease.period 30000 HMaster server lease period in milliseconds. Default is 30 seconds. Region servers must report in within this period else they are considered dead. On loaded cluster, may need to up this period. hbase.regionserver.lease.period 30000 HRegion server lease period in milliseconds. Default is 30 seconds. Clients must report in within this period else they are considered dead. hbase.server.thread.wakefrequency 10000 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 10 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.regionserver.msginterval 15000 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.regionserver.maxlogentries 30000 Rotate the logs when count of entries exceeds this value. Default: 30,000 hbase.hregion.maxunflushed 10000 Memcache will be flushed to disk if number of Memcache writes are in excess of this number. hbase.hregion.max.filesize 134217728 Maximum desired file size for an HRegion. If filesize exceeds value + (value / 2), the HRegion is split in two. Default: 128M.
