Dears, I use hadoop-0.16.4 to do some work and found a error which i can't get the reasons.
The scenario is like this: In the reduce step, instead of using OutputCollector to write result, i use FSDataOutputStream to write result to files on HDFS(becouse i want to split the result by some rules). After the job finished, i found that *some* files(but not all) are empty on HDFS. But i'm sure in the reduce step the files are not empty since i added some logs to read the generated file. It seems that some file's contents are lost after the reduce step. Is anyone happen to face such errors? or it's a hadoop bug? Please help me to find the reason if you some guys know Thanks & Regards Guangfeng -- Guangfeng Jin Software Engineer iZENEsoft (Shanghai) Co., Ltd
