Hey guys,
thanks for the replies.
1. "Requesting new TaskExecutor" looks fine as it's exactly 32 as is jobs'
parallelism set.
The weird thing is that after those 32 containers requested and received we
have this "flood" of 'Received new container/Returning excess container`
(and as shown below it's actually doing something on YARN side)
Where does those come from?
2. I felt that DEBUG will be needed, we'll see what we can do about it.
3. Yes, all in favor for upgrading to 1.5.4. But as Gary mentioned there
seems to be no fixes that could heal it (I was reading release notes
previous to posting this thread ; )).
4. Hadoop: 2.6.0+cdh5.14.0
Here are logs for one of "excess" containers:
