> I am trying to use "skip failed records" map-reduce functionality during the map phase.
I created special testing file with 8 corrupted records. I am using TextInputFormat and during
the processing (of the record) map function fails with unhandled exception (parsing the record
into expected structure). Job is using the old mapred api.
> My job settings for enabling "skip failed records feature":
>     <property>
>         <name>mapred.skip.mode.enabled</name>
>         <value>true</value>
>     </property>
>     <property>
>         <name>mapreduce.map.maxattempts</name>
>         <value>10</value>
>     </property>
>     <property>
>         <name>mapreduce.task.skip.start.attempts</name>
>         <value>1</value>
>     </property>
>     <property>
>         <name>mapreduce.map.skip.maxrecords</name>
>         <value>1</value>
>     </property>
> I verified that those properties are propagated via verification in job.xml. 
> I am using hadoop 2.2.0 (HDP 2.0). Job is still failing after 10 attempts.
> UPDATE:
> - obviously job is not entering skip record mode
> Q: Does this feature works on RecordReader level only? Hadoop definite guide (which is
for v.1) descibes thais feature at the level of map/reduce funciton
