-improve performance of avro map reduce jobs
ey-chih chow 2011-06-24, 23:55
Our Map/Reduce jobs are all based on avro. We would like to enhance their performance. The objects collected in our mappers and reducers are mainly of the type GenericData.Record. Currently, most of jobs are CPU, rather than IO, bound. Can anybody suggest ways to improve the performance of the jobs? Thanks a lot.
