Hi,
We have a requirement to process only new files in HDFS on a daily basis. I
am sure this is a general requirement in many ETL kind of processing
scenarios. Just wondering if there is a way to identify new files that are
added to a path in HDFS? For example, assume already some files were

Hi,
I have a basic question regarding file writes and reads in HDFS. Is the
file write and read process a sequential activity or executed in parallel?
For example, lets assume that there is a File File1 which constitutes of
three blocks B1, B2 and B3.
1. Will the write process write B2 only afte
text/videos to get the insight.
Best of luck
