-----------------------------------------------
Added a test to reproduce bug: https://reviews.apache.org/r/31951/
> Slaves sends mutated copy of executorinfo to new elected master
> ---------------------------------------------------------------
>
> Key: MESOS-2463
> URL: https://issues.apache.org/jira/browse/MESOS-2463
> Project: Mesos
> Issue Type: Bug
> Affects Versions: 0.22.0
> Reporter: Chi Zhang
> Assignee: Kapil Arya
> Priority: Blocker
> Labels: mesosphere
> Fix For: 0.22.0
>
>
> {code}
> static ExecutorInfo decorateExecutorEnvironment(
> ExecutorInfo executorInfo,
> const TaskInfo& taskInfo)
> {
> // Merge environment variables retrieved from label-decorator hooks.
> executorInfo.mutable_command()->mutable_environment()->MergeFrom(
> HookManager::slaveLaunchExecutorEnvironmentDecorator(
> executorInfo,
> taskInfo));
> return executorInfo;
> }
> {code}
> does a default allocation of environment, even when the original ExecutorInfo
> doesn't have one set.
> When a new master is elected and receives this copy, it would reject tasks
> for the same Executor because of this difference:
> Existing ExecutorInfo has :
> command {
> uris
> { value: "/usr/local/bin/gc_executor" executable: true }
> environment {
> }
> value: "./gc_executor"
> }
> framework_id
> { value: "201103282247-0000000019-0000" }
> ------------------------------------------------------------
> New Task's ExecutorInfo has:
> command {
> uris
> { value: "/usr/local/bin/gc_executor" executable: true }
> value: "./gc_executor"
> }
> framework_id
> { value: "201103282247-0000000019-0000" }
