Zhe Zhang commented on HDFS-9173:
---------------------------------
Great work Walter! It's probably simpler to treat data and parity blocks
uniformly here. We can calculate "safe length" as the smallest length that
covers at least 6 internal blocks. In your example, that would be the length of
blk_5. We can then leave all data/parity blocks smaller than this length as
stale replicas. {{ErasureCodingWorker}} will take care of replacing them.
