> From the email thread:
> 1) LB, when stored as directories, adds a lot of low-level complexity to Hive 
> tables that has to be accounted for in many places in the code where the 
> files are written or modified - from FSOP to ACID/replication/export.
> 2) While working on some FSOP code I noticed that some of that logic is 
> broken - e.g. the duplicate file removal from tasks, a pretty fundamental 
> correctness feature in Hive, may be broken. LB also doesn’t appear to be 
> compatible with e.g. regular bucketing.
> 3) The feature hasn’t seen development activity in a while; it also doesn’t 
> appear to be used a lot.
> Keeping with the theme of cleaning up “legacy” code for 3.0, I was proposing 
> we remove it.
> (2) also suggested that, if needed, it might be easier to implement similar 
> functionality by adding some flexibility to partitions (which LB directories 
> look like anyway); that would also keep the logic on a higher level of 
> abstraction (split generation, partition pruning) as opposed to many 
> low-level places like FSOP, etc.
