环境: CentOS 6.4,  Myriad

Myriad是一个支持yarn的mesos框架 ，用于整合yarn和mesos资源管理。

编译如下：

git clone https://github.com/mesos/myriad.git

由于gradle被墙了（真不知道为什么要墙住这个软件，万恶的gfw），只好从 http://get.jenv.mvnsearch.org/download/gradle/gradle-2.4.zip 下载，将其放在myriad/gradle/wrapper目录下。修改gradle-wrapper.properties配置文件，

vi myriad/gradle/wrapper/gradle-wrapper.properties

#Wed Jun 10 10:58:12 CDT 2015
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
#distributionUrl=https\\\\://services.gradle.org/distributions/gradle-2.4-bin.zip
distributionUrl=gradle-2.4.zip

注释掉原有的distributionURL，并新增。

最后编译文件

cd myriad

./gradlew build

配置和启用myriad

复制相应库到目录下

sudo cp myriad/myriad-executor/build/libs/myriad-executor-runnable-0.0.1.jar /usr/local/libexec/mesos
sudo cp myrida/myriad-scheduler/build/libs/*.jar /usr/lib/hadoop-yarn/
