Subject [jira] [Commented] (HBASE-16055) PutSortReducer loses any Visibility/acl attribute set on the Puts
Date Thu, 23 Jun 2016 08:34:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16055?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15346053#comment-15346053

ramkrishna.s.vasudevan commented on HBASE-16055:
------------------------------------------------

bq.So here the user account, with which the Reducer gets run, should have SYSTEM visibility
label. We have to document that as well?
Yes. Infact interacting that User I wanted to raise the JIRA. Will raise one and have some
things to discuss with respect to it.
bq.Chances are less, still if the cell is already having some tags with it, we should not
be loosing them.
Here we will not be having any tags. Because these cells are from Puts. currently we don't
support Tags to be added with Puts. So should be fine I think.

> Based on a user discussion, I think as the user pointed out rightly, when a PutSortReducer
is used any visibility attribute or external attribute set on the Put will be lost as we create
KVs out of the cells in the puts whereas the ACL and visibility are all set as Attributes.

> In TextSortReducer we tend to read the information we tend to read the information from
the parsed line but here in PutSortReducer we don't do it. I think this problem should be
in all the existing versions where we support Tags. Correct me if am wrong here.
