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.

> We need a seek functionality, which could be able to let clients seek to a position and
start writing from there. For writing, a seek can leave a hole in the file.
