Rhadoop使用中数据被修改的问题

zbzjy2008

求助啊 用rhadoop处理数据的时候发现数据的某些字段被莫名其妙的改变了 analysislog<-function(input,output,pattern="\\|"){     mapper<-function(.,records){       names(records)<-c("src_ip","dst_ip","src_port","dst_port","app_type","app_id","up_bytes","down_bytes",                          "proto","ip_ver","begin_time","end_time")       data<-records[-1,]       keyval("key",data)      }       reducer<-function(key,data){       keyval(key,data)     }     mapreduce(input = input ,output = output,input.format=make.input.format("csv",sep="|"),               map = mapper, reduce = reducer,combine = T#,backend.parameters = list(hadoop = list(D ="mapred.reduce.tasks=8"))              ) } analysislog("/log_test","/logtmp","\\|") 这样不做任何处理 只是把文件输出后 发现记录的某些字段改变了 原始数据： root@ubuntu22:~/log# find app_stat-20140117-000571.r |xargs grep "000080fe000000000edd5679f93fdcfa" 000080fe000000000edd5679f93fdcfa|000002ff00000000000000000c000000|27655|27655|0|0|10906|0|17|6|2014.01.17 01:19:00|2014.01.17 01:19:50 000080fe000000000edd5679f93fdcfa|000002ff00000000000000000c000000|27655|27655|0|0|11114|0|17|6|2014.01.17 01:19:50|2014.01.17 01:19:54 000080fe000000000edd5679f93fdcfa|000002ff000000000000000003000100|5568|60180|0|0|336|0|17|6|2014.01.17 01:19:00|2014.01.17 01:20:01 000080fe000000000edd5679f93fdcfa|000002ff00000000000000000c000000|27655|27655|0|0|10923|0|17|6|2014.01.17 01:19:55|2014.01.17 01:20:02 000080fe000000000edd5679f93fdcfa|000002ff00000000000000000c000000|3821|27655|0|0|3600|0|17|6|2014.01.17 01:19:57|2014.01.17 01:20:13 经过rhadoop后: hadoop@ubuntu22:/home/hadoop/Rhadoop$ find output |xargs grep "000080fe000000000edd5679f93fdcfa" "000080fe000000000edd5679f93fdcfa","000002ff00000000000000000c000000",27655,27655,0,0,10923,0,17,6,"2014.01.17 01:19:55","2014.01.17 01:20:02" "000080fe000000000edd5679f93fdcfa","000002ff00000000000000000c000000",3821,27655,0,0,3600,0,17,6,"2014.01.17 01:19:57","2014.01.17 01:20:13" "000080fe000000000edd5679f93fdcfa","000002ff00000000000000000c000000",180,92,1,1,30,1,1,2,"2014.01.17 01:19:00","2014.01.17 01:19:50" "000080fe000000000edd5679f93fdcfa","000002ff00000000000000000c000000",180,92,1,1,37,1,1,2,"2014.01.17 01:19:50","2014.01.17 01:19:54" "000080fe000000000edd5679f93fdcfa","000002ff000000000000000003000100",494,185,1,1,238,1,1,2,"2014.01.17 01:19:00","2014.01.17 01:20:01" 求大神指点啊！！！！！
