libprotoc 2.5.0

2 安装CMake 

apt-get

										install cmake

asn@hadoop1:~/Desktop$ cmake --version

cmake version 2.8.12.2

3、安装其他依赖

sudo apt-get install zlib1g-dev libssl-dev

4 Snappy压缩

cd snappy-1.1.2/

sudo ./configure

sudo make

sudo make install

asn@hadoop1:~/snappy-1.1.2$ ls /usr/local/lib | grep snappy

libsnappy.a

libsnappy.la

libsnappy.so

libsnappy.so.1

libsnappy.so.1.2.1

-L/usr/local/lib -ljvm -ldl -O2 -m64 -O2 -Wl,-soname -Wl,libhadoopsnappy.so.0 -o .libs/libhadoopsnappy.so.0.0.1

这是因为没有把安装jvm的libjvm.so symbolic链接到usr/local/lib。

如果你的系统是64位，可到/root/bin/jdk1.6.0_37/jre/lib/amd64/server/察看libjvm.so 链接到的地方，这里修改如下，使用命令：

$ sudo ln -s /usr/local/jdk1.6.0_45/jre/lib/amd64/server/libjvm.so /usr/local/lib/

问题即可解决。

http://osdn.jp/projects/sfnet_findbugs/downloads/findbugs/3.0.1/findbugs-3.0.1.zip/

asn@hadoop1:~$ unzip -h

UnZip 6.00 of 20 April 2009, by Debian. Original by Info-ZIP.

Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]

Default action is to extract files in list, except those in xlist, to exdir;

file[.zip] may be a wildcard. -Z => ZipInfo mode ("unzip -Z" for usage).

-p extract files to pipe, no messages -l list files (short format)

-f freshen existing files, create none -t test compressed archive data

-u update files, create if necessary -z display archive comment only

-v list verbosely/show version info -T timestamp archive to latest

-x exclude files that follow (in xlist) -d extract files into exdir

modifiers:

-n never overwrite existing files -q quiet mode (-qq => quieter)

-o overwrite files WITHOUT prompting -a auto-convert any text files

-j junk paths (do not make directories) -aa treat ALL files as text

-U use escapes for all non-ASCII Unicode -UU ignore any Unicode fields

-C match filenames case-insensitively -L make (some) names lowercase

-X restore UID/GID info -V retain VMS version numbers

-K keep setuid/setgid/tacky permissions -M pipe through "more" pager

-O CHARSET specify a character encoding for DOS, Windows and OS/2 archives

-I CHARSET specify a character encoding for UNIX and other archives

See "unzip -hh" or unzip.txt for more help. Examples:

unzip data1 -x joe => extract all files except joe from zipfile data1.zip

unzip -p foo | more => send contents of foo.zip via pipe into program more

unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer

asn@hadoop1:~$ sudo unzip findbugs-3.0.1.zip -d /usr/local

配置环境变量

# findbugs

1)etc配置

core-site.xml

<configuration>

<property>

<name>fs.defaultFS</name>

<value>hdfs://localhost:9000</value>

</property>

<property>

<name>hadoop.tmp.dir</name>

<value>file:/home/asn/tmp</value>

<value>1</value>

</property>

<property>

<name>dfs.webhdfs.enabled</name>

<value>true</value>

</property>

</configuration>

2) 格式化namenode

$ bin/hdfs namenode -format

3) 启动NameNode和DataNode后台进程

$ sbin/start-dfs.sh

asn@hadoop1:~/hadoop-2.6.0-cdh5.4.4$ sbin/start-dfs.sh

Starting namenodes on [localhost]

localhost: starting namenode, logging to /home/asn/hadoop-2.6.0-cdh5.4.4/logs/hadoop-asn-namenode-hadoop1.out

localhost: datanode running as process 44763. Stop it first.

Starting secondary namenodes [0.0.0.0]

0.0.0.0: secondarynamenode running as process 44939. Stop it first.

4) 运行例子grep

$ bin/hdfs dfs -mkdir /user

$ bin/hdfs dfs -mkdir /user/asn

$ bin/hdfs dfs -put etc/hadoop input

$ bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.0-cdh5.4.4.jar grep input output 'dfs[a-z.]+'

5) 查看结果

asn@hadoop1:~/hadoop-2.6.0-cdh5.4.4$ bin/hdfs dfs -get output output ##从hdfs文件系统中拷贝输出文件到本地

asn@hadoop1:~/hadoop-2.6.0-cdh5.4.4$ ls

8 端口总结

dfs.namenode.http-address

0.0.0.0:50070

The address and the base port where the dfs namenode web ui will listen on.

分布式文件系统NameNode节点web ui界面的监听端口

dfs.namenode.secondary.http-address

0.0.0.0:50090

The secondary namenode http server address and port.

dfs.datanode.http.address

0.0.0.0:50075

The datanode http server address and port.

dfs文件系统服务暴露在9000端口

重新生成ssh-key时，报错处理

asn@hadoop1:~/hadoop-2.6.0-cdh5.4.4$ ssh localhost

Agent admitted failure to sign using the key.

解决办法

在当前用户下执行命令：

ssh-add
