Ignore Some Failed Tasks in MapReduce


In Pig, we can below for MRv1
set mapred.max.map.failures.percent 100
mapred.max.reduce.failures.percent 100
mapred.map.tasks.speculative.execution false

And for MRv2
mapreduce.map.failures.maxpercent 100
mapreduce.reduce.failures.maxpercent 100
mapreduce.map.speculative false
