Subject Re: spark and mesos issue

It might not be related only to memory issue. Memory issue is also
there as you mentioned. I have seen that one too. The fine mode issue
is mainly spark considering that it got two different block manager
for same ID, whereas if I search for the ID in the mesos slave, it
exist only on the one slave not on multiple of them. Theis might be
due to the size of ID, as spark out the error as

14/09/16 08:04:29 ERROR BlockManagerMasterActor: Got two different
block manager registrations on 20140822-112818-711206558-5050-25951-0

where as in the mesos slave I see logs as

I0915 20:55:18.293903 31434 containerizer.cpp:392] Starting container
'3aab2237-d32f-470d-a206-7bada454ad3f' for executor

you the last 3 digits of ID are missing in spark where as they are
different in mesos slaves.
