new 2e09aec [HUDI-1319] Make async operations work with metadata table
(#2332)
2e09aec is described below
commit 2e09aeca47a7f14cd83f644a5132d4dfd0f27813

[HUDI-1319] Make async operations work with metadata table (#2332)
- Changes the syncing model to only move over completed instants on data
timeline
- Syncing happens postCommit and on writeClient initialization
- Latest delta commit on the metadata table is sufficient as the watermark
for data timeline archival
- Cleaning/Compaction use a suffix to the last instant written to metadata
table, such that we keep the 1-1
- .. mapping between data and metadata timelines.
- Got rid of a lot of the complexity around checking for valid commits
during open of base/log files
- Tests now use local FS, to simulate more failure scenarios
- Some failure scenarios exposed HUDI-1434, which is needed for MOR to
work correctly
