Subject Re: ignoring map task failure
Date Wed, 20 Aug 2014 09:04:58 GMT
Hi,

Please check the value of mapreduce.map.maxattempts and
mapreduce.reduce.maxattempts. If you'd like to ignore the error only
in specific jobs, it's useful to use -D option to change the
configuration as follows:

bin/hadoop jar job.jar -Dmapreduce.map.maxattempts=10

Thanks,
- Tsuyoshi
