So the file name in hdfs is (for the collector sink example given earlier): POC_Hadoop_Client_1-20120119-160450707-0600.604742529713813.00000021
The following makes sense: POC_Hadoop_Client_1-20120119 But what comes after it (-160450707-0600.604742529713813.00000021)does not make sense? Also if one file is divided into multiple files in hdfs, how do I know the chronology (ie what comes first - what is the header, what is the end of that file?)

So if your file takes longer than that to read, send to collector, acknowledge and write to HDFS youre gonna end up with more that one file on HDFS.
