Konstantin Shvachko commented on HDFS-7740:
-------------------------------------------
Scenario for the test:
- Create file with 3 DNs up. Kill DN(0). Truncate file. Restart DN(0), make
sure the old replica is disregarded and replaced with the truncated one.
- Kill DN(1). Truncate within the same last block with copy-on-truncate.
Restart DN(1), verify replica consistency.
> Test truncate with DataNodes restarting
