[jira] Created: (HADOOP-1868) [hbase] Make default configuration
more responsive
[hbase] Make default configuration more responsive
--------------------------------------------------
Key: HADOOP-1868
URL: https://issues.apache.org/jira/browse/HADOOP-1868
Project: Hadoop
Issue Type: Improvement
Components: contrib/hbase
Reporter: stack
Priority: Minor
Fix For: 0.15.0
Default configuration is not very first-time user friendly. Creating a table takes 30 seconds on my desktop. The bulk of the time is hbase just sitting in the sleep it does between wakes looking for work. Hbase can be made more responsive by tuning down a couple of parameters without compromizing operation on single node up to small cluster size (10s of machines).

Attachment: responsive.txt
Here's a patch to change two parameters. Tables are now created and dropped in 10 seconds rather than 30. I also tried these params on our small cluster under load.
{code}
<name>hbase.client.pause</name>
- <value>30000</value>
+ <value>10000</value>
<description>General client pause value. Used mostly as value to wait
before running a retry of a failed get, region lookup, etc.</description>
