Nick Dimiduk updated HBASE-13323:
---------------------------------
Labels: beginner (was: )
> Audit behavior heterogenous node capacity
> -----------------------------------------
>
> Key: HBASE-13323
> URL: https://issues.apache.org/jira/browse/HBASE-13323
> Project: HBase
> Issue Type: Task
> Components: Balancer
> Reporter: Nick Dimiduk
> Labels: beginner
>
> From the thread "introducing nodes w/ more storage"
> (http://search-hadoop.com/m/DHED4azyle2), we should have a look at what
> happens when nodes of varying data density are used in a single cluster. The
> user would expect that nodes be filled according to their capacity, meaning
> an "even distribution" looks like all nodes at the same pct use. This
> behavior is probably in the intersection of hbase balancer and hdfs balancer.
> Probably this is made more complex by recent HDFS features such as HDFS-5682.
> After investigation, let's fix it up to work better (if it's broken), and
> document the behavior in our awesome book.
