clj-hbase

HBase client for Clojure.

Although other HBase clients exist I wanted to learn more about the API and evolve a client library for experimenting with HBase. This repository will chart my progress :)

Usage

; config currently is read from the ./resources directory
; where it expects to have core-site.xml and hbase-site.xml
; that tell the client how to connect to the cluster.
(def config (create-config))

Creating and Listing tables

(with-connection config
  (list-tables))
; ()

(def admin (create-administrator config))
(create-table admin "MyFirstTable")
(with-connection config
  (list-tables))

; ({:name "MyFirstTable"})

Storing rows

(with-table config "PaulsFirstTable"
  (put (.getBytes "key1")
       (.getBytes "family1")
       (.getBytes "colA")
       1 ; timestamp/version
       (.getBytes "This is my value")))

Retrieving rows

(with-table config "PaulsFirstTable"
  (fetch (.getBytes "key1")))
