Hi, I wonder that if Hadoop can solve effectively the question as following: ========================================== input file: a.txt, b.txt result: c.txt a.txt: id1,name1,age1,... id2,name2,age2,... id3,name3,age3,... id4,name4,age4,... b.txt: id1,address1,... id2,address2,... id3,address3,...
c.txt id1,name1,age1,address1,... id2,name2,age2,address2,... ======================================== I know that it can be done well by database. But I want to handle it with hadoop if possible. Can hadoop meet the requirement? Any suggestion can help me. Thank you very much! Best Regards, Gump
