Chi Zhang created MESOS-2463:
--------------------------------
Summary: 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
Reporter: Chi Zhang
Priority: Blocker
{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 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" }
