- Users using spark.executor.cores > 1 used to fail due to "FileSystem closed"
- This is due to HoodieWrapperFileSystem closing the wrapped filesytem obj
- FileSystem.getInternal caching code races threads and closes the extra fs instance(s)
- Bumped up num cores in tests to 8, speeds up tests by 3-4 mins
- For implicit indexes (e.g BloomIndex), don't buffer up written records
- By default, only collect 10% of failing records to avoid OOMs
- Improves debuggability via above, since data errors can now show up in collect()
- Unit tests & fixing subclasses & adjusting tests
- Added a precondition check, otherwise incr pull could miss commits
- Lowered default cleaner retention to 10, to enable simpler understanding for newbies
- Bumped down min/max instants to retain as well
