> compaction thread throttle value is not correct in hbase-default.xml

> Key: HBASE-12682
> URL: https://issues.apache.org/jira/browse/HBASE-12682
> Project: HBase
> Issue Type: Bug
> Components: regionserver

> While doing some compaction tuning and looking up some of the parameters, I
> noticed that hbase.regionserver.thread.compaction.throttle default value in
> the documentation and in hbase-site.xml seems to be off the mark.
> {code}
> <property>
> <name>hbase.regionserver.thread.compaction.throttle</name>
> <value>2560</value>
> <description>There are two different thread pools for compactions, one
> for large compactions and
> the other for small compactions. This helps to keep compaction of lean
> tables (such as
> <systemitem>hbase:meta</systemitem>) fast. If a compaction is larger
> than this threshold, it
> goes into the large compaction pool. In most cases, the default value
> is appropriate. Default:
> 2 x hbase.hstore.compaction.max x hbase.hregion.memstore.flush.size
> (which defaults to 128).
> The value field assumes that the value of
> hbase.hregion.memstore.flush.size is unchanged from
> the default.</description>
> </property>
> {code}
> It should be in bytes. Or am I missing anything?
> It is not a problem in 0.98 since the property is not in hbase-site.xml over
> there. It is obtained dynamically:
> {code}
> throttlePoint = conf.getLong("hbase.regionserver.thread.compaction.throttle",
> 2 * maxFilesToCompact * storeConfigInfo.getMemstoreFlushSize());
> {code}
