Dinesh S. Atreya commented on HADOOP-5215:
------------------------------------------
Please see HDFS-9607 only for *_random updates, random write-in-place, random
read-write, specifically random read-copy-write_* that intends to avoid (does
not allow) holes.
Seek API support is also included along with random updates.
> Add seek functionality for writes into file interfaces
