No. See log below. Btw: the job is not cleaned up properly. Some task remain in state "Canceling".
The program I execute is "Streaming WordCount" example with my own
source function. This custom source (see below), reads a local (small)
file, bufferes each line in an internal buffer, and emits the buffered
lines over and over again (for 5 minutes). (A copy of the file is
located on every worker machine of course.) This is of course no common
patttern; I just do this, because I have only a small file and want the
job to run longer.
As the job is running for multiple minutes until it fails, I assume that
this uncommon pattern should actually not cauase any problem. I just
report it, to make sure it is not the problem (hope you can confirm).
