Steve Loughran resolved HADOOP-14561.
-------------------------------------
Resolution: Won't Fix
Problem here is that the Hadoop APIs don't let us seek() into a file and
overwrite bits of it; all you get is append(), and that isn't supported in many
filesystems.
Even with append(), that'd force a move to some log-structured format where all
changes went in at the end...that'd get expensive fast if you were updating
large files inside the HAR.
Have to close as a wontfix, unless anyone can come up with a better solution.
> Making HAR mutable

> HAR files are immutable, thus even minimal changes to an existing HAR file
> results in new HAR file. So, making HAR mutable would be beneficial.
