Subject Re: Hbase 0.2.6 performance

bq. and hadoop 1.0.4

Were you using the same hadoop version for testing 0.20.6 ?

Please consider using hadoop 1.2.1 for testing. See HBASE-9799 Change
Hadoop 1.2 dependency to 1.2.1

I assume you used default parameters for 0.94.12
How about 0.20.6 - did you tune parameters for that ?

Were you loading data into the same table at the time of performing query
testing ?

Thanks
