Vinod Kone updated MESOS-6299:
------------------------------
Description:
In `Master::_accept()` there are cases when a task is not launched (e.g, agent
disconnected, agent removed or task group is invalid). Doesn't look like we
make sure the task is removed from `framework->pending` in this case. In
addition to the memory leak reconciliation will result in a scheduler thinking
the task is still in TASK_STAGING. Same for operators who are looking at
operator endpoints.
Note that pending task not being removed when agent is disconnected/removed is
a long standing bug. We should fix it in all the supported versions.
