Subject [jira] [Commented] (HBASE-4917) CRUD Verify Utility
Date Wed, 25 Jan 2012 19:53:53 GMT

Mubarak Seyed commented on HBASE-4917:
--------------------------------------

@Nicolas,

How different this LoadTest tool from PerformanceEvaluation 

{code}
hbase org.apache.hadoop.hbase.PerformanceEvaluation
Usage: java org.apache.hadoop.hbase.PerformanceEvaluation \
  [--miniCluster] [--nomapred] [--rows=ROWS] <command> <nclients>
{code}

I believe LoadTester.java generates load for multiple column families (provided there is an
external properties file to define the CFs and their definition, read/write threads, regions/server)
where as PerformanceEvaluation uses only one CF (TestTable:info).

How does LoadTester differ from YCSB, i believe YCSB supports only one CF as well.

I think LoadTester can be used for burn-in test (when we provision a new cluster and sniff
the cluster). 

If no one is working on this issue, i can help porting loadtest to src/test/java/org/apache/hadoop/hbase/loadtest.

Thanks.

> Add a verify utility to run basic CRUD tests against hbase in various common use cases.
 This is great for sanity checking a cluster setup because it can be run as a one line shell
command with no required params.  Multiple column families for different use-cases can be
tested together.  Currently provided use-cases are 'action log', 'snapshot' and 'search'.
The interface is developed such that it can be easily extended to cover more use-cases.
