> StochasticLoadBalancer RegionLoads aren’t being used in RegionLoad cost
> functions
> ---------------------------------------------------------------------------------
>
> Key: HBASE-21439
> URL: https://issues.apache.org/jira/browse/HBASE-21439
> Project: HBase
> Issue Type: Bug
> Components: Balancer
> Affects Versions: 1.3.2.1, 2.0.2
> Reporter: Ben Lau
> Assignee: Ben Lau
> Priority: Major
> Fix For: 3.0.0
>
> Attachments: HBASE-21439-addendum-master.patch,
> HBASE-21439-branch-1.patch, HBASE-21439-master.patch
>
>
> In StochasticLoadBalancer.updateRegionLoad() the region loads are being put
> into the map with Bytes.toString(regionName).
> First, this is a problem because Bytes.toString() assumes that the byte array
> is a UTF8 encoded String but there is no guarantee that regionName bytes are
> legal UTF8.
> Secondly, in BaseLoadBalancer.registerRegion, we are reading the region loads
> out of the load map not using Bytes.toString() but using
> region.getRegionNameAsString() and region.getEncodedName(). So the load
> balancer will not see or use any of the cluster's RegionLoad history.
> There are 2 primary ways to solve this issue, assuming we want to stay with
> String keys for the load map (seems reasonable to aid debugging). We can
> either fix updateRegionLoad to store the regionName as a string properly or
> we can update both the reader & writer to use a new common valid String
> representation.
> Will post a patch assuming we want to pursue the original intention, i.e.
> store regionNameAsAString for the loadmap key, but I'm open to fixing this a
> different way.
