Help

A good starting place is probably the HBase internal shell help:

$ cd /path/to/hbase/bin/
$ ./hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 0.90.4, r1150278, Sun Jul 24 15:53:29 PDT 2011

hbase(main):001:0> help<Enter>

Configuration

See Apache HBase Configuration.

Stopping HBase

Sometimes the usual ./stop-hbase.sh won't stop all processes (especially if you messed up configuration/dependencies). This is how you can kill all remaining ones:

$ cd /tmp
$ cat hbase*
; will print some PIDs
$ kill -9 <pid> ; for every PID

Notes

• HBase provides a web interface on port 60010 (master) and 60030 (region). So if HBase is running on localhost you can access it under http://localhost:60010 and http://localhost:60030.
• Loopback IP must be 127.0.0.1. This is not the case for current Ubuntu versions. See Why does HBase care about /etc/hosts?
