impala编译安装_impala 编译

前言

本文主要关于Impala-cdh5-2.12.0_5.16.1 源码编译与安装~

背景

公司需要将hdfs迁移到腾讯云的chdfs。chdfs实现了hdfs的协议，可以按照数据实际内存来付费，会节省不少钱。然而在测试过程中发现impala并不兼容chdfs会上报不支持ofs。需要改动内核源码~。根据腾讯云同事提供的部分源码改动方案改完后，需要自己打包编译。下面大概记录下编译遇到的一些坑

E0312 14:35:09.345242 358875 impala-server.cc:285] Currently configured default filesystem: CHDFSHadoopFileSystemAdapter. fs.defaultFS (ofs://f4mjxuquwlp-p2WP.chdfs.ap-shanghai.myqcloud.com/) is not supported

源码下载

https://codeload.github.com/cloudera/Impala/zip/cdh5-2.12.0_5.16.1

yum 安装依赖

yum -y install git ant libevent-devel automake libtool flex bison gcc-c++ openssl-devel make cmake
yum -y install doxygen.x86_64 glib-devel python-devel bzip2-devel svn libevent-devel krb5-workstation
yum -y install openldap-devel db4-devel python-setuptools python-pip cyrus-sasl* postgresql postgresql-server ant-nodeps lzo-devel lzop

编译

1、设置环境变量 IMPALA_HOME
2、设置 /etc/default/bigtop-utils 中的JAVA_HOME
3、编译命令 ./buildall.sh -notests -so

编译过程中遇到的问题和解决方案

1、下载python包过慢

日志可以看出会去下载python包，如果已经存在就跳过，由于服务器下载比较慢，有些包可以手动下载完丢进去。目录如下：
$IMPALA_HOME/infra/python/deps/

下载部分代码在 ./buildall.sh

bootstrap_dependencies() {
  # Populate necessary thirdparty components unless it's set to be skipped.
  if [[ "${SKIP_TOOLCHAIN_BOOTSTRAP}" = true ]]; then
    echo "SKIP_TOOLCHAIN_BOOTSTRAP is true, skipping download of Python dependencies."
    echo "SKIP_TOOLCHAIN_BOOTSTRAP is true, skipping toolchain bootstrap."
  else
    echo "Downloading Python dependencies"
    # Download all the Python dependencies we need before doing anything
    # of substance. Does not re-download anything that is already present.
    // 下载python包
    if ! "$IMPALA_HOME/infra/python/deps/download_requirements"; then
      echo "Warning: Unable to download Python requirements."
      echo "Warning: bootstrap_virtualenv or other Python-based tooling may fail."
    else
      echo "Finished downloading Python dependencies"
    fi

    echo "Downloading and extracting toolchain dependencies."
    "$IMPALA_HOME/bin/bootstrap_toolchain.py"
    echo "Toolchain bootstrap complete."
  fi
}

下载过慢的话可以手动下载丢入上面的包。还有后面编译的时候可以把上面下载的那段代码注释掉，跳过校验。校验也是比较慢的，~~~~~

2、下载c++的包过慢
Downloading and extracting toolchain dependencies.
impala编译过程在python包下载后回去下载c++的包。同样下载会很慢，可以自行下载后丢入。
目录为：$IMPALA_HOME//toolchain/

3、jar包下载失败
我在编译 fe这个项目的时候碰到了失败。主要原因是pom文件中的jar包下载不到，有些包已经不存在配置的仓库源里了。可能版本比较老了…
错误如下，有蛮多这种包找不到的，还有下载慢的。下载慢的自己下载放到本地仓库~~

[WARNING] The POM for net.sourceforge.czt.dev:cup-maven-plugin:jar:1.6-cdh is missing, no dependency information available

经过不断尝试发现需要修改 impala-parent 工程下的pom.xml。手动添加一些仓库地址

END：经历九九八十一难 最终编译成功了~~~

部署

一、修改三个配置文件
1、 bin/start-catalogd.sh 启动catalog的文件会去连接metastore
需要增加
source $IMPALA_HOME/bin/impala-config.sh
CATALOGD_ARGS=" -log_dir=/var/log/impala "
2、bin/start-statestored.sh 跟踪集群中的Impalad的健康状态及位置信息
需要增加
source $IMPALA_HOME/bin/impala-config.sh
STATESTORED_ARGS="-log_dir=/var/log/impala -state_store_port=24000"
3、bin/set-classpath.sh

4、bin/start-impalad.sh

二、启动
2972 2021-03-14 17:00:30 nohup ./start-statestored.sh &
2973 2021-03-14 17:00:34 nohup ./start-catalogd.sh &
2974 2021-03-14 17:00:38 nohup ./start-impalad.sh & 计算节点只要启动这个即可
三、连接测试

结语

1、编译impala需要一定的耐心，很多包下载很慢很慢。。
2、对maven配置的不熟悉导致走了很多弯路~~~~~准备好好学习下maven配置管理
补充一下mvn下载日志可以去 $IMPALA_HOME/logs 下查看。可以看到具体的下载进度~
