Nishith Agarwal commented on HUDI-409:
--------------------------------------
No, the delta/log files can contain multiple log blocks. Each of these blocks
contain a magic header to differentiate each other in the bytestream written to
disk (a single file). Right now, it is possible for the magic header to clash
with the data and hence corrupting the reader. We need a way to generate a
secure hash to avoid that scenario
> Replace Log Magic header with a secure hash to avoid clashes with data
