Hello My simple mapreduce program takes text as input and outputs the same text to different directories depending on the values in each record using Multipleoutputs API where i specify the baseoutputpath.
it works fine for small data sets. But when it takes 2 GB It strucks either at MAP 100% REDUCE 0% (MAP -ONLY where reducers are set=0) or MAP 100% REDUCE 100%.(if reducers not set =0) Logs say all mappers and reducers are succeeded. There is no calculation in Driver Class even. Mine is 8 Node Cluster with 8GB RAM each. Please Let me know where might be the problem. Thanks in advance. Have a nice weekend Anusha
