With values 1620 for base ports, 99 additional RegionServers can be supported, on a server. Since HBase version 1.1.0, HMaster doesn’t use region server ports, this leaves 10 ports (16020 to 1600 to 16039) to be used for RegionServers.įor supporting additional RegionServers, set environment variables HBASE_RS_BASE_PORT and HBASE_RS_INFO_BASE_PORT to appropriate values before running script local-regionservers.sh.Į.g. It works in a similar way to the local-master-backup.sh command, in that each parameter you provide represents the port offset for an instance.Įach RegionServer requires two ports, and the default ports are 1600. The local-regionservers.sh command allows you to run multiple RegionServers. Running multiple HRegionServers on the same system can be useful for testing in pseudo-distributed mode. Generally, one HRegionServer runs per node in the cluster. The HRegionServer manages the data in its StoreFiles as directed by the HMaster. Submit the tests and/or the metrics so that other users can gain certainty about Proof that a feature designated as /not tested/ does work in a given way, please It is an unknown, and there are no guarantees.
