部署impala

impala安装选择rpm包方式进行,这是本次部署唯一一个主要主件采用rpm方式进行安装部署,这里主要原因是cloudera没有提供现成的tar包文件,而源码编译过程会出现各种未知原因,为了方便采用以下方式进行部署。

安装介质如下:

$ ls

[hadoop@db01 impala270]$

1、安装bigtop和sentry

$sudo yum -y install redhat-lsb

sudo rpm -ivh bigtop-utils-0.7.0+cdh5.10.0+0-1.cdh5.10.0.p0.71.el7.noarch.rpm

    1:sentry-1.5.1+cdh5.10.0+272-1.cdh5################################# [100%]

2、impalad安装

注:impalad需安装在所有datanode服务器上。

sudo rpm -ivh impala-2.7.0+cdh5.10.0+0-1.cdh5.10.0.p0.71.el7.x86_64.rpm --nodeps

warning: impala-2.7.0+cdh5.10.0+0-1.cdh5.10.0.p0.71.el7.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID e8f86acd: NOKEY

Updating / installing...
    1:impala-2.7.0+cdh5.10.0+0-1.cdh5.1################################# [100%]

3、安装impala server

sudo rpm -ivh impala-server-2.7.0+cdh5.10.0+0-1.cdh5.10.0.p0.71.el7.x86_64.rpm

warning: impala-server-2.7.0+cdh5.10.0+0-1.cdh5.10.0.p0.71.el7.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID e8f86acd: NOKEY

Updating / installing...
    1:impala-server-2.7.0+cdh5.10.0+0-1################################# [100%]
   
    --以上步骤在所有datanode节点安装
   

4、修改配置文件

sudo vim /etc/default/impala

IMPALA_CATALOG_SERVICE_HOST=db01

IMPALA_STATE_STORE_HOST=db01

这两个ip是要装CATALOG和STATE_STORE的节点,

CATALOG和STATE_STORE这两个服务必须和hive装在同一个节点

在一个节点编辑后,复制到其他节点

sudo scp /etc/default/impala db02:/etc/default/impala

sudo scp /etc/default/impala db03:/etc/default/impala

sudo scp /etc/default/impala db04:/etc/default/impala

vim /etc/default/bigtop-utils

export JAVA_HOME=/opt/service/jdk1.7.0_67

scp bigtop-utils db02:/etc/default/bigtop-utils

scp bigtop-utils db03:/etc/default/bigtop-utils

scp bigtop-utils db04:/etc/default/bigtop-utils

vim hdfs-site.xml

<property>
                 <name>dfs.datanode.hdfs-blocks-metadata.enabled</name>
                 <value>true</value>
      </property>
      <property>
                 <name>dfs.client.file-block-storage-locations.timeout.millis</name>
                 <value>10000</value>
      </property>

5、复制hive和hadoop的配置文件到impala

sudo scp /opt/cdh5/hive-1.1.0-cdh5.10.0/conf/hive-site.xml db01:/etc/impala/conf/

sudo scp /opt/cdh5/hive-1.1.0-cdh5.10.0/conf/hive-site.xml db02:/etc/impala/conf/

sudo scp /opt/cdh5/hive-1.1.0-cdh5.10.0/conf/hive-site.xml db03:/etc/impala/conf/

sudo scp /opt/cdh5/hive-1.1.0-cdh5.10.0/conf/hive-site.xml db04:/etc/impala/conf/

sudo scp /opt/cdh5/hadoop-2.6.0-cdh5.10.0/etc/hadoop/core-site.xml db01:/etc/impala/conf/

sudo scp /opt/cdh5/hadoop-2.6.0-cdh5.10.0/etc/hadoop/core-site.xml db02:/etc/impala/conf/

sudo scp /opt/cdh5/hadoop-2.6.0-cdh5.10.0/etc/hadoop/core-site.xml db03:/etc/impala/conf/

sudo scp /opt/cdh5/hadoop-2.6.0-cdh5.10.0/etc/hadoop/core-site.xml db04:/etc/impala/conf/

sudo scp /opt/cdh5/hadoop-2.6.0-cdh5.10.0/etc/hadoop/hdfs-site.xml db01:/etc/impala/conf/

sudo scp /opt/cdh5/hadoop-2.6.0-cdh5.10.0/etc/hadoop/hdfs-site.xml db02:/etc/impala/conf/

sudo scp /opt/cdh5/hadoop-2.6.0-cdh5.10.0/etc/hadoop/hdfs-site.xml db03:/etc/impala/conf/

sudo scp /opt/cdh5/hadoop-2.6.0-cdh5.10.0/etc/hadoop/hdfs-site.xml db04:/etc/impala/conf/

6、在hive节点安装impala-state-store 和impala-catalog

$ sudo rpm -ivh impala-state-store-2.7.0+cdh5.10.0+0-1.cdh5.10.0.p0.71.el7.x86_64.rpm

warning: impala-state-store-2.7.0+cdh5.10.0+0-1.cdh5.10.0.p0.71.el7.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID e8f86acd: NOKEY

$ sudo rpm -ivh impala-catalog-2.7.0+cdh5.10.0+0-1.cdh5.10.0.p0.71.el7.x86_64.rpm

warning: impala-catalog-2.7.0+cdh5.10.0+0-1.cdh5.10.0.p0.71.el7.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID e8f86acd: NOKEY

Preparing...                          ################################# [100%]

Updating / installing...
    1:impala-catalog-2.7.0+cdh5.10.0+0-################################# [100%]

$ sudo cp /mnt/mysql-connector-java-5.1.22-bin.jar /var/lib/impala/

7、所有节点安装impala shell

sudo yum -y install python-setuptools
  sudo rpm -ivh impala-shell-2.7.0+cdh5.10.0+0-1.cdh5.10.0.p0.71.el7.x86_64.rpm
 

8、修改impala依赖jar包,通过软连接方式

sudo rm -rf /usr/lib/impala/lib/hadoop-annotations.jar

sudo rm -rf /usr/lib/impala/lib/hadoop-auth.jar

sudo rm -rf /usr/lib/impala/lib/hadoop-aws.jar

9、启动impala

#安装了hive的节点启动state-store和catalog服务

service impala-state-store start

service impala-catalog start

#所有datanode节点启动impalad

service impala-server start
