Ted Yu reopened HBASE-2706:
---------------------------
> Use heuristics to adjust various parameters based on load characteristics
> -------------------------------------------------------------------------
>
> Key: HBASE-2706
> URL: https://issues.apache.org/jira/browse/HBASE-2706
> Project: HBase
> Issue Type: New Feature
> Components: master
> Affects Versions: 0.20.4
> Reporter: Ted Yu
>
> Refer to 'ideas to improve throughput of the base writing' discussion on
> hbase user mailing list.
> We should use heuristics to adjust various parameters based on load
> characteristics. Factors include, but not limited to, number of CPU (cores)
> on each node, amount of physical memory on each node, Heap space allocated to
> master/region servers.
> HBase parameters shown below would be dynamic whose current values can be
> seen on master.jsp / regionserver.jsp
> For JVM parameters such as -Xmx, master.jsp should display recommended value
> to user.

> Thanks. I will make this change:
> <property>
> <name>hbase.hregion.memstore.block.multiplier</name>
> <value>8</value>
> </property>
> <property>
> <name>hbase.regionserver.msginterval</name>
> <value>10000</value>
> </property>
> <property>
> <name>hbase.hstore.compactionThreshold</name>
> <value>6</value>
> </property>
> <property>
> <name>hbase.hstore.blockingStoreFiles</name>
> <value>18</value>
> </property>
> and see how it goes.

> With the above change, the write goes faster if it works, but now we have
> problem that the
> insertion doesn't work at all, here is the result:
> 2010-06-09 22:29:04,330 WARN org.apache.hadoop.hdfs.DFSClient: DFS Read:

> .IOException: Could not find target position 0
