Azkaban 常见错误

1. 创建project时ERROR: Insert projecttest for existing project failed.

创建project时报ERROR: Insert projecttest for existing project failed.错误，需要检查项目名称和描述中是否有中文。

2. 首次运行时可能的报错ERROR [ExecutorServlet] [Azkaban] executor became inactive before setting up the flow 1 azkaban.executor.ExecutorManagerException: executor became inactive before setting up the flow 1

需要手动去激活一下 executor，方式如下：

curl -G "localhost:$(<./executor.port)/executor?action=activate" && echo

3. 执行 Flow 一直处于 Preparing 状态

修改 web-server conf/azkaban.properties 配置
execute 主机过滤器配置, 去掉 MinimumFreeMemory
MinimumFreeMemory 过滤器会检查 executor 主机空余内存是否会大于 6G，如果不足 6G，则 web-server 不会将任务交由该主机执行
