@srowen - sorry for the unnecessary noise.
Typically in our clusters, we see few machine reboot every hour. We are
trying to run Spark jobs which are processing around 100TB of data and runs for
several hours. During the run of the job, it very common to see several machine
reboot and fetch failures as a result. The longer the job runs, more fetch
failure it encounters. That is why we want _the number of consecutive failures_
configurable.
