Billy Pearson commented on HADOOP-2138:
---------------------------------------
>From what I understand about writing files to data nodes I do not thank is is
>a major problem. If the regions are not located on the host serving server on
>the first compaction they would be stored local first and stay local from
>there on out unless the current servers hard drive is full and it has to store
>it on a different server. Over all the region servers would self fix this
>problem by default over time.
So only time this would be an issue is on a restart or after a failed region
server.
> [hbase] Master should allocate regions to the regionserver hosting the region
> data where possible

> Currently, regions are assigned regionservers based off a basic loading
> attribute. A factor to include in the assignment calcuation is the location
> of the region in hdfs; i.e. servers hosting region replicas. If the cluster
> is such that regionservers are being run on the same nodes as those running
> hdfs, then ideally the regionserver for a particular region should be running
> on the same server as hosts a region replica.
