1.环境准备
想要更进一步了解和使用Trafodion,难免不得不自己尝试一番编译源码，此为之前做的一个小任务，踩过一些坑，现分享出来并做个总结。[参考](https://cwiki.apache.org/confluence/display/TRAFOdioN/Build+Source)
1.1 虚拟机
源码编译准备搭建自己的一个虚拟机，系统CentOS6.X即可，7版本会编译错误不支持。
配置参考：
硬盘：30G 最好不要默认，否则多次编译会使磁盘空间不足
内存：2G
网卡：NAT
Tips:避免出错需要重新新建虚拟机，最好每做一步做好快照，方便恢复。
查看系统版本：
cat /etc/redhat-release
CentOS release 6.7 (Final)
1.2 安装编译需要的包
# Install first to avoid dependency problems for the steps below
sudo yum install epel-release
sudo yum install alsa-lib-devel ant ant-nodeps apr-devel apr-util-devel \ boost-devel cmake device-mapper-multipath dhcp doxygen flex \ gcc-c++ gd git glibc-devel glibc-devel.i686 graphviz-perl gzip \ java-1.7.0-openjdk-devel libX11-devel libXau-devel libaio-devel \ libcurl-devel libibcm.i686 libibumad-devel libibumad-devel.i686 \ libiodbc libiodbc-devel librdmacm-devel librdmacm-devel.i686 \ libxml2-devel lua-devel lzo-minilzo \ net-snmp-devel net-snmp-perl openldap-clients openldap-devel \ openldap-devel.i686 openmotif openssl-devel openssl-devel.i686 \ perl-Config-IniFiles perl-Config-Tiny \ perl-DBD-sqlite perl-Expect perl-IO-Tty perl-Math-Calc-Units \ perl-Params-Validate perl-Parse-RecDescent perl-TermReadKey \ perl-Time-HiRes protobuf-compiler protobuf-devel \ readline-devel rpm-build saslwrapper sqlite-devel \ unixODBC unixODBC-devel uuid-perl wget xerces-c-devel xinetd
Tips: 避免因为包安装失败造成编译错误，请确保每一个包均安装成功
1.3 配置
配置java的环境变量，通过java -version 验证成功
mkdir trafodion
cd trafodion
git clone git://git.apache.org/incubator-trafodion.git
mkdir ~/trafodion-download ~/trafodion-build-tools
cd ~/mysource/incubator-trafodion/install
./traf_tools_setup.sh -d ~/trafodion-download -i ~/trafodion-build-tools

dest-mpich-3.0.4
icu4c_4.4
thrift-0.9.0
udis86-1.7.2
zookeeper-3.4.5
Tips : 此过程需要从网络上下载包并解压安装，由于网络限制，速度较慢，一般在1-1.5h
安装完成导入环境变量，后续需要使用，否则因为找不到变量而发生错误
export TOOLSDIR=$HOME/trafodion-build-tools
echo -en "export TOOLSDIR=$HOME/trafodion-build-tools\n" >> $HOME/.bashrc
本步骤结束，请验证
$JAVA_HOME
$TOOLSDIR
是否有值
2.编译
源码编译一般来说有debug和release两种方式，但是debug多用于开发百衲衣测试，在正式的环境中编译请推荐使用release方式
Tips：debug方式我没有编译成功过，具体问题需要待研究
d <Trafodion source directory>/core/sqf
source ./sqenvr.sh
cd ../..
执行 make all
或者make package-all(后续就不需要安装local_hadoop)
[INFO] Building jar: /home/trafdeveloper/mysource/incubator-trafodion/dcs/target/dcs-1.3.0.jar
[INFO] Building tar: /home/trafdeveloper/mysource/incubator-trafodion/dcs/target/dcs-1.3.0.tar.gz
[INFO] BUILD SUCCESS
mkdir -p ../distribution

Tips:这部分完成需要验证编译情况
sqvers -u

3.搭建测试环境
编译完成，我们需要配置SSH免登录和测试一下环境服务
3.1 ssh 免登录
ssh-keygen -t rsa -N "" -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/id_rsa
echo "NoHostAuthenticationForLocalhost=yes" >>~/.ssh/config
chmod go-w ~/.ssh/config
chmod 755 ~/.ssh
3.2 修改默认配置
edit /etc/security/limits.conf and reboot the server
* - core 1000000
* - nproc 267263
* - nofile 32000
* - sigpending 515196
* - memlock 49595556
* - stack 10240
3.3 安装local_hadoop
如果前面编译make package-all，这步可不需要
d <Trafodion source directory>/core/sqf
source ./sqenvr.sh
cd ../..
cds
install_local_hadoop
Checking for existing Hadoop processes...
The testware tpcds_kit.zip does not exist and will not be installed
This testware is needed to run developer HIVE regression tests
.
.
.
Installed directory size and name = 2.7G /home/trafdeveloper/mysource/incubator-trafodion/core/sqf/sql/local_hadoop
Setup is complete. You can use the convenience scripts starting with sw... located in /home/trafdeveloper/mysource/incubator-trafodion/core/sqf/sql/scripts.
$ ./install_traf_components

.
.
.
Configuration scripts for DCS,TRAFCI and Phoenix test are set up
Open a new session and start Trafodion by executing sqgen and sqstart scripts
./install_traf_components
3.4 测试服务
测试服务状态
swstatus
# 无报错，打印两行字大致是所有服务以启动即可
# 一般HBase 没有正常启动
执行
swstarthbase 启动HMaster
#
sqgen
# 重新打开终端，引入源，执行
sqstart
所有服务启动正常，没有down的服务即大功告成
4.总结
1.以上Tips都是常遇到的错误，请注意
2.Trafodion 基于hadoop的基础
最后欢迎一起讨论学习Trafodion，支持企业版Esgyn
