Jingcheng Du commented on HBASE-13693:
--------------------------------------
Sorry for the late comments.
Thanks for the patch [~ashutosh_jindal].
Actually in mob, we have several places to instantiate the writer, in HMobStore
and MobUtils (the code in MobUtils is used by MobFileCompactor and Sweeper).
But there is only one place in HMobStore is touched in this patch. Do we need
to add the encrypt context to the other place? Thanks.
[~jmhsieh], this patch is not completed, do we need to reopen it? Please
advise. Thanks.

> Mob HFiles are not encrypting.
> steps to reproduce:
> ===============
> 1.create a table and for column family with mob enabled and enable AES
> encryption for the column family.
> 2. Insert mob data into the table.
> 3. Flush the mob table.
> 4. check hfiles for mob data is created or not.
> 5. check hfiles in hdfs is encrypted or not using hfile tool.
> {code}
> hfile tool output for mob reference hfile meta
> Block index size as per heapsize: 392
