FAILURE: Integrated in HBase-1.3-IT #408 (See
[https://builds.apache.org/job/HBase-1.3-IT/408/])
HBASE-15026 The default value of "hbase.regions.slop" in docs is (tedyu: rev
c2256bd2ae39611dec36ad83abde38f14c641192)
* hbase-common/src/main/resources/hbase-default.xml

> Key: HBASE-15026
> URL: https://issues.apache.org/jira/browse/HBASE-15026
> Project: HBase
> Issue Type: Bug
> Components: Balancer
> Affects Versions: 1.1.2
> Reporter: Tianyin Xu
> Assignee: Tianyin Xu
> Priority: Minor
> Fix For: 2.0.0, 1.3.0
>
> Attachments: HBASE.15026.patch
>
>
> The default value of {{hbase.regions.slop}} is {{0.001}} in
> {{StochasticLoadBalancer}} (which is the default setting of
> {{hbase.master.loadbalancer.class}}).
> However, in the docs (both {{hbase-default.xml}} and [online
> docs|http://hbase.apache.org/book.html#config.files]), the default value is
> {{0.2}}. This value is specified in {{BaseLoadBalancer}} (which is an
> abstract class) and is inherited by {{SimpleLoadBalancer}}. However, as
> {{SimpleLoadBalancer}} is no longer used as the default load balancer, the
> doc is obsolete.
> The code structure is:
> {code:title=BaseLoadBalancer.java|borderStyle=solid}
> public abstract class BaseLoadBalancer implements LoadBalancer {
> ...
> protected void setSlop(Configuration conf) {
> this.slop = conf.getFloat("hbase.regions.slop", (float) 0.2);
> }
> {code}
> {code:title=StochasticLoadBalancer.java|borderStyle=solid}
> public class StochasticLoadBalancer extends BaseLoadBalancer {
> ...
> @Override
> protected void setSlop(Configuration conf) {
> this.slop = conf.getFloat("hbase.regions.slop", 0.001F);
> }
> {code}
> I suggest to make the manual entry of {{hbase.regions.slop}} specify the
> different default values in different balancer classes.
