操作系统是Ubuntu Server 12.10
先安装Thrift
代码语言:javascript复制sudo apt-get install libboost-dev libboost-test-dev
libboost-program-options-dev libevent-dev automake
libtool flex bison pkg-config g libssl-dev
如果你还要使用别的语言,也需要安装对应的包
- Ruby
- ruby-full ruby-dev librspec-ruby rake rubygems libdaemons-ruby libgemplugin-ruby mongrel
- Python
- python-dev python-twisted
- Perl
- libbit-vector-perl
- Php, install
- php5-dev php5-cli
- C_glib
- libglib2.0-dev
- Erlang
- erlang-base erlang-eunit erlang-dev
- Csharp
- mono-gmcs libmono-dev libmono-system-web2.0-cil
- Haskell
- ghc6 cabal-install libghc6-binary-dev libghc6-network-dev libghc6-http-dev
cd thrift
./bootstrap.sh
./configure --with-boost=/usr/local
make
make install
安装Hbase
修改源码包中的conf/hbase-site.xml文件。替换成以下内容:
代码语言:javascript复制 hbase.rootdir
file:///DIRECTORY/hbase
hbase.zookeeper.property.dataDir
/DIRECTORY/zookeeper
替换上文中对应的目录位置
修改conf/hbase-env.sh 添加JAVA_HOME export JAVA_HOME=/usr/local/jdk
启动Hbase
代码语言:javascript复制$ ./bin/start-hbase.sh
starting Master, logging to logs/hbase-user-master-example.org.out
$ ./bin/hbase shell
HBase Shell; enter 'help' for list of supported commands.
Type "exit" to leave the HBase Shell
Version 0.94.2, r1395367, Sun Oct 7 19:11:01 UTC 2012
hbase(main):001:0>
hbase(main):001:0> create 't1','cf'
0 row(s) in 1.6600 seconds
hbase(main):002:0> list

t1
1 row(s) in 0.0130 seconds
hbase(main):004:0> put 't1', 'row1', 'cf:a', 'value1'

hbase(main):005:0> put 't1', 'row2', 'cf:a', 'value2'

hbase(main):006:0> put 't1', 'row3', 'cf:a', 'value3'
0 row(s) in 0.0040 seconds
hbase(main):007:0> scan 't1'
ROW COLUMN CELL
row1 column=cf:a, timestamp=1352453214504, value=value1
row2 column=cf:a, timestamp=1352453236805, value=value2
row3 column=cf:a, timestamp=1352453244172, value=value3
3 row(s) in 0.0320 seconds
hbase(main):008:0> get 't1', 'row1'
COLUMN CELL
cf:a timestamp=1352453214504, value=value1
1 row(s) in 0.0120 seconds
hbase(main):009:0> disable 't1'
0 row(s) in 2.0510 seconds
hbase(main):011:0> drop 't1'
0 row(s) in 1.0480 seconds
hbase(main):012:0> exit
</pre>
如果上述测试脚本都能正常执行,就证明你Hbase安装成功了。
注意,如果你使用ubuntu,当执行命令的时候,提示
ERROR: org.apache.hadoop.hbase.PleaseHoldException: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing
在logs/hbase-*-ubuntu.log中显示类似
Failed setting up proxy interface org.apache.hadoop.hbase.ipc.HRegionInterface to localhost/127.0.0.1:55915 after attempts=1
Caused by: java.net.ConnectException: Connection refused
出现这种情形,请检查/etc/hosts文件,把
127.0.1.1 ubuntu
改成
127.0.0.1 ubuntu
之后重新启动Hbase就可以正常运行了。
### 通过Thrift操作Hbase
生产Thrift客户端
mkdir ~/thrift
cd ~/thrift
thrift --gen erl [hbase-root]/src/main/resources/org/apache/hadoop/hbase/thrift/Hbase.thrift
启动两个客户端
$ cd ~/hbase
$ ./bin/start-hbase.sh
在另外一个客户端,启动Thrift Server
$ cd ~/hbase
elton@ubuntu:~/hbase$ ./bin/hbase thrift start
12/11/09 17:41:33 INFO util.VersionInfo: HBase 0.94.2
...
12/11/09 17:41:35 DEBUG thrift.ThriftServerRunner: Using binary protocol
12/11/09 17:41:35 INFO thrift.ThriftServerRunner: starting TBoundedThreadPoolServer on /0.0.0.0:9090; min worker threads=16, max worker threads=1000, max queued requests=1000
之后就可以产生一个gen-erl,进入它,编译其中的Erlang源文件
cd gen-erl
erlc *.erl
在gen-erl目录下,进入erlang shell。
$ erl
Erlang R15B02 (erts-5.9.2) [source] [64-bit] [smp:4:4] [async-threads:0] [hipe] [kernel-poll:false]
Eshell V5.9.2 (abort with ^G)

true,true}},
0}}
