Subject [jira] [Commented] (HBASE-12332) [mob] use filelink instad of retry when resolving an hfilelink.
Date Fri, 12 Dec 2014 08:03:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14243847#comment-14243847

Jingcheng Du commented on HBASE-12332:

Hi Jon [~jmhsieh]. We've added the test case in the patch of HBASE-12673, and make sure the
current implementation could work well with this above case. Please help review and comment.
The mob ref cell in the HBase only contains the mob file name (not the HFileLink pattern),
it's hard to know whether the mob file is a HFileLink in the read path. Instead reading the
file via the value of the ref cell in HBase (which is a mob file name, not a HFileLink pattern)
through the read paths(two possible locations) is much easier. How do you think about this?

> 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.
