1.下载ambari-impala-service

VERSION=`hdp-select status hadoop-client | sed 's/hadoop-client - \([0-9]\.[0-9]\).*/\1/'`
sudo git clone https://github.com/cas-bigdatalab/ambari-impala-service.git /var/lib/ambari-server/resources/stacks/HDP/$VERSION/services/IMPALA

2./etc/yum.repos.d新建impala.repo

[cloudera-cdh5]
# Packages for Cloudera's Distribution for Hadoop, Version 5, on RedHat	or CentOS 6 x86_64
name=Cloudera's Distribution for Hadoop, Version 5
baseurl=https://archive.cloudera.com/cdh5/redhat/7/x86_64/cdh/5.8.0
gpgkey =https://archive.cloudera.com/cdh5/redhat/7/x86_64/cdh/RPM-GPG-KEY-cloudera
gpgcheck = 1

3.重启ambari-server

sudo service ambari-server restart

4.安装impala

Actions-->Add service -->impala，然后一步一步安装

 

中间发生一次报错信息：

Traceback (most recent call last):
  File "/var/lib/ambari-agent/cache/stack-hooks/before-ANY/scripts/hook.py", line 38, in <module>
    BeforeAnyHook().execute()

KeyError: u'impala'
Error: Error: Unable to run the custom hook script ['/usr/bin/python', '/var/lib/ambari-agent/cache/stack-hooks/before-ANY/scripts/hook.py', 'ANY', '/var/lib/ambari-agent/data/command-863.json', '/

1 命令行

# cd /var/lib/ambari-server/resources/scripts
# python configs.py -u admin -p admin -n $cluster_name -l $ambari_server -t 8080 -a get -c cluster-env |grep -i ignore_groupsusers_create
"ignore_groupsusers_create": "false",
# python configs.py -u admin -p admin -n $cluster_name -l $ambari_server -t 8080 -a set -c cluster-env -k ignore_groupsusers_create -v true

详细参数详见

# python configs.py --help

2 rest api

curl --user admin:admin -i -H ‘X-Requested-By: ambari‘ -X GET "http://ambari.server:8080/api/v1/clusters/$cluster_name/configurations?type=cluster-env"

从返回的items中找到tag，然后再请求（增加tag参数）：

curl --user admin:admin -i -H ‘X-Requested-By: ambari‘ -X GET "http://ambari.server:8080/api/v1/clusters/$cluster_name/configurations?type=cluster-env&tag=$tag"

返回结果中包含所有的property

"properties" : {
"agent_mounts_ignore_list" : "",
"alerts_repeat_tolerance" : "1",
"enable_external_ranger" : "false",
"fetch_nonlocal_groups" : "true",
"hide_yarn_memory_widget" : "false",
"ignore_bad_mounts" : "false",
"ignore_groupsusers_create" : "false",

修改需要先将上面的配置保存到一个文件，比如/tmp/configurations.tmp，然后修改，然后再调用接口:

curl --user admin:admin -i -H ‘X-Requested-By: ambari‘ -X PUT -d @/tmp/configurations.tmp http://ambari.server:8080/api/v1/clusters/$cluster_name

然后再安装即可；

因为要去cloudera官网下载impala的rpm文件，安装过程比较慢，可能会失败，多试几次就好了

如果需要重装 报错

需要执行

yum clean all
yum list update
yum makecache
yum repolist

5.hdfs增加配置

#HDFS config we need add below config to /etc/hadoop/conf/core-site.xml
<property>
    <name>dfs.client.read.shortcircuit</name> 
   <value>true</value>
</property>

    <name>dfs.client.read.shortcircuit.skip.checksum</name>
        <value>false</value>

<property> 
    <name>dfs.datanode.hdfs-blocks-metadata.enabled</name> 
    <value>true</value>
</property>

 6.重启hdfs

7.启动impala

报错：

cat impala-server.log （每台impala机器都要做）

vim /etc/default/bigtop-utils

JAVA_HOME=/opt/jdk1.8.0_201 （与/etc/profile保持一样）

把hbase的jar包拷贝到 /usr/lib/impala/lib 并创建软连接

这里注意根据安装的impala的版本对应的cdh的版本选择对应的hbase的版本，否则可能出现版本不兼容的问题
