Tsz Wo Nicholas Sze commented on HDFS-9173:
-------------------------------------------
> getSafeLength already handles this case. It sorts all lengths and gets the

It does not seem correct if we have hflush. Here is an example:
{code}
blk_0 blk_1 blk_2 blk_3 blk_4 blk_5 blk_6 blk_7 blk_8
64k 64k 64k 64k 4k 0k 64k 64k 64k
{code}
Suppose blk_4 and blk_5 are unavailable. The code will mistakenly consider
this as a full strip.
