How sequence files are getting generated (System commands) in Hadoop HDFS

[Saurabh_Khairnar]

Hi Team,

Could you please let us know - How the sequence files get generated in Hadoop HDFS ? (From Replicate to HDFS)

- Are the files created and written to in a single operation, are temporary files created and then copied or renamed, are they first created and then appended to, or other possible combinations ?

Thanks and Regards,

Saurabh
