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?)

Thanks
Gaurav

Subject: Re: Collector Sink writing to HDFS

If youre using default flume-site.xml, it will open a new file every
30 seconds for writing to HDFS. 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.
