SHELL USAGE:

Quote all names in HBase Shell such as table and column names.  Commas delimit

command parameters.  Type <RETURN> after entering a command to run it.

Dictionaries of configuration used in the creation and alteration of tables are

Ruby Hashes. They look like this:

  {'key1' => 'value1', 'key2' => 'value2', ...}

and are opened and closed with curley-braces.  Key/values are delimited by the

'=>' character combination.  Usually keys are predefined constants such as

NAME, VERSIONS, COMPRESSION, etc.  Constants do not need to be quoted.  Type

'Object.constants' to see a (messy) list of all constants in the environment.

If you are using binary keys or values and need to enter them in the shell, use

double-quote'd hexadecimal representation. For example:

  hbase> get 't1', "key\x03\x3f\xcd"

  hbase> get 't1', "key\003\023\011"

  hbase> put 't1', "test\xef\xff", 'f1:', "\x01\x33\x40"

The HBase shell is the (J)Ruby IRB with the above HBase-specific commands added.
