Is that also possible to control which disk the blocks are assigned?
Say when there are multiple disks on one node, I wish the blocks belong to the
local region distribute evenly across the disks.
At present, it seems to that it is not. Though if you take non local regions'
replica blocks in
This sounds hugely useful to me and is one of those why doesn't HBase have

Is there an issue to watch?

HBASE Performance Monitoring -
The feature depends on hdfs support.
Once we have that, we can implement this feature in HBase.

I'll raise a jira shortly (couldn't locate jiras that talk about this)

But as it stands, I take it that people here finds this feature
beneficial (although not many people chimed in yet). Yes, we'd
probably need to work with Hadoop core to see this feature go through.
It'll be
There is a jira after all. It is HBASE-4755.

The main motivation is to maintain good performance on RS failovers.
This is also tied with hdfs and its block placement policy. Let me
explain as I understand it. If we control the hdfs block placement
strategy we can write all blocks for a hfile (or for all hfiles
related to a region) to the
