Azkaban 设置 Multiple Executor Mode

设置multiple Executor mode

即在azkaban-web-server中的azkaban.properties添加：

Multiple Executor Mode

azkaban.use.multiple.executors=true
azkaban.executorselector.filters=StaticRemainingFlowSize,MinimumFreeMemory,CpuStatus
azkaban.executorselector.comparator.NumberOfAssignedFlowComparator=1
azkaban.executorselector.comparator.Memory=1
azkaban.executorselector.comparator.LastDispatched=1
azkaban.executorselector.comparator.CpuUsage=1

比较因子为NumberOfAssignedFlowComparator、Memory、LastDispatched、CpuUsage 默认权重都是1
同时在数据库中插入Executor：

insert into executors(host,port) values("ExecutorIP",12321);
