Yes, here it is: https://reviews.apache.org/r/65630/ > On Feb. 13, 2018, 9:38 a.m., Vinod Kone wrote: > > src/slave/slave.cpp > > Lines 1109-1111 (patched) > > <https://reviews.apache.org/r/65570/diff/2/?file=1955934#file1955934line1109> > > > > I don't think we need this check.

The reason is, if we do not have this check, that means we will do attach as long as the task's ContainerInfo has a `SANDBOX_PATH` volume with type `PARENT`, but such attach will fail (see below) because the executor's volume directory is not created yet at the moment when `attachTaskVolumeDirectory` is called, it will actually be created by the `volume/sandbox_path` isolator when launching the nested container. ``` E0212 22:23:08.905462 10350 slave.cpp:1009] Failed to attach '/home/qzhang/opt/mesos/slaves/54de35d5-250f-4bf9-9444-3633c5e66e7d-S0/frameworks/54de35d5-250f-4bf9-9444-3633c5e66e7d-0000/executors/default-executor/runs/0ea4dc53-e543-42c4-8bb5-c5b667eee4c0/foo' to virtual path '/home/qzhang/opt/mesos/slaves/54de35d5-250f-4bf9-9444-3633c5e66e7d-S0/frameworks/54de35d5-250f-4bf9-9444-3633c5e66e7d-0000/executors/default-executor/runs/0ea4dc53-e543-42c4-8bb5-c5b667eee4c0/tasks/test/xxx': Failed to get realpath of '/home/qzhang/opt/mesos/slaves/54de35d5-250f-4bf9-9444-3633c5e66e7d-S0/frameworks/54de35d5-250f-4bf9-9444-3633c5e66e7d-0000/executors/default-executor/runs/0ea4dc53-e543-42c4-8bb5-c5b667eee4c0/foo': No such file or directory ``` So I think we still need this check which will ensure the executor's volume directory exists before we do the attach, the executor's volume directory will actually be created by the `filesystem/linux` isolator when launching the executor. - Qian ----------------------------------------------------------- This is an automatically generated e-mail.
