Subject [jira] [Commented] (HBASE-12332) [mob] use filelink instead of retry when resolving mobfiles
Date Tue, 23 Dec 2014 05:57:13 GMT

Jiajia Li commented on HBASE-12332:
-----------------------------------

hi, [~jon@cloudera.com], in this patch, I found each reading mob cell operate will create
the HFileLink and StoreFileInfo, will this reduce the efficiency of reading? I think through
reading the possible locations will be easier and more effective, how do you think?

> 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.
