前面已经完成Zookeeper和HDFS的安装,本文会详细介绍Hbase的安装步骤。以及安装过程中遇到问题的汇总。

下面开始Hbase的安装。
Hbase的服务器规划

192.168.67.101 c6701
--Master + regionserver
192.168.67.102 c6702
--Master(standby)+regionserver
192.168.67.103 c6703
--regionserver
|
---在c6701上安装Hbase
1. 创建hbase用户,及创建相关目录

su - root
useradd hbase
echo
"hbase:hbase"
| chpasswd
mkdir -p /data/zookeeper
mkdir -p /data/hbase/tmp
mkdir -p /data/hbase/logs
chown -R hbase:hbase /data/hbase
chown -R a+rx /home/hdfs <<<<<<<<<<<<<让hadoop目录,其他人可以用读和执行
--很重要hbase需要访问
|
2. 解压软件

su - hbase
cd /tmp/software
tar -zxvf hbase-1.1.3.tar.gz -C /home/hbase/

---安装c6702的hbase
7. 创建hbase用户
1
|
ssh c6702
"useradd hbase;echo "
hbase:hbase
" | chpasswd"
|
8. 为hbase用户ssh免密
1
|
ssh-copy-id hbase@c6702
|
9. 拷贝软件,创建目录,解压软件

|
scp -r /tmp/software/hbase-1.1.3.tar.gz root@c6702:/tmp/software/.
ssh c6702
"chmod 777 /tmp/software/*;mkdir -p /data/zookeeper;mkdir -p /data/hbase/tmp;mkdir -p /data/hbase/logs;chown -R hbase:hbase /data/hbase"
ssh c6702
"chmod -R a+rx /home/hdfs"
ssh hbase@c6702
"tar -zxvf /tmp/software/hbase-1.1.3.tar.gz -C /home/hbase"

HBASE安装过程,问题汇总
1. 首先Hbase-site.xml设置错误,ns是namenode的名字,Hbase可以访问很多HDFS,在这里标注namenode,才是指定访问这个namenode,实际在hdfs看到是/hbase的目录,不会看到ns的。
1
2
|
<
name
>hbase.rootdir</
name
>
<value>hdfs://ns/hbase</value> <<<<<<<<<<<<<<<<<这里要注意
|
2.通过hbase访问hdfs遇到问题,虽然也可以对hdfs操作,但是有warning

[root@c6701 home]# su - hbase
$ hdfs dfs -mkdir /hbase
$ hdfs dfs -ls /
Found 1 items
drwxrwx
--- - hdfs hadoop 0 2017-10-25 10:18 /hbase
权限不对,需要hbase是owner才可以让hbase正常访问hdfs路径
$ hadoop fs -chown hbase:hbase /hbase
$ hdfs dfs -ls /
Found 1 items
drwxrwx
--- - hbase hbase 0 2017-10-25 10:18 /hbase
已经修改成功
[hbase@c6701 ~]$ hdfs dfs -ls /hbase/test
17/09/27 07:45:59 WARN util.NativeCodeLoader: Unable
to
load
native-hadoop library
for
your platform... using builtin-java classes
where
applicable
|
最后注释掉/etc/profile中的CLASSPATH=解决的这个问题
1

|
export JAVA_HOME=/usr/
local
/jdk1.8.0_144
export JRE_HOME=/usr/
local
/jdk1.8.0_144/jre
#export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$PATH:/home/hbase/hbase-1.1.3/bin
|
3. 启动Hbase的时候,还遇到权限问题,无法找到hadoop。首先通过hbase用户检查hadoop访问权限
1
2
|
su - hbase
/home/hdfs/hadoop-2.6.0-EDH-0u2/bin/hadoop version
|
如果权限有问题,需要增加hbase执行hadoop文件的权限
4. 启动过程中,遇到错误,是由于/home/hbase/hbase-1.1.3/lib/原有的一些jar包版本与hadoop不同,进而影响,删除即可。hbase会从hadoop中读取jar包

至此Zookeeper+HDFS+Hbase安装全部完成,前面还是比较顺利的,但是在Hbase安装的过程中,由于与Hadoop的衔接上,出现一些问题,耗费一些时间分析解决。
后续会继续测试,hadoop升级的过程。
