Subject [jira] [Commented] (HBASE-12332) [mob] use filelink instad of retry when resolving an hfilelink.
Date Fri, 24 Oct 2014 02:16:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14182317#comment-14182317

Jingcheng Du commented on HBASE-12332:

Do we need to do this for snapshot?
Actually in the mob, the hfilelinks are not used in the read path. The Mob has four candidate
paths in reading after the snapshot ( mob working, mob archive, source mob working and source
mob archive), these paths are known without parsing the hfilelink. So is it necessary to detour
through the hfilelink?
One more thing is HFileLink can be only parsed its name to a hbase working/archive dir, it's
a new problem to let it parse the file name to a mob dir.
Please advise. Thanks.

> in the snapshot code, hmobstore was modified to traverse an hfile link to a mob.   Ideally
this should use the transparent filelink code to read the data.
> Also there will likely be some issues with the mob file cache with these links.
