satishkotha opened a new pull request #2918:
URL: https://github.com/apache/hudi/pull/2918
## What is the purpose of the pull request
Add support for reusing fileId in clustering execution strategy. This is
strategy specific. Default is still to create new files
## Brief change log
Some datasets rely on external index. We cannot change record location for
clustering (because external index doesn't support update). We can still take
advantage of clustering by doing 'local' sorting within each file. Add support
for such strategies.
Also, made small changes on how metadata is generated after clustering is
complete. (metadata is getting generated redundantly twice before. Removed 1 to
make it simple).
