Subject can I do this to get a sample benchmark...
Date Thu, 09 Dec 2010 00:57:15 GMT
I would really just like to insert 1,000,000 rows on 2 machines like so

 

[root@localhost hadoop]# ./bin/hadoop
org.apache.hadoop.hbase.PerformanceEvalua

tion --rows=1000000 sequentialWrite 2

 

and then insert 1,000,000 rows on 3 machines

 

[root@localhost hadoop]# ./bin/hadoop
org.apache.hadoop.hbase.PerformanceEvalua

tion --rows=1000000 sequentialWrite 3

 

but when I ran the first test and then looked at the size afterwards, I
had 3.6 gigs on one

node and 0 gigs on the other node.  I have dfs.replication set to 1(ie.
I don't want it for

this test right now).  I am just trying to play with the system a bit
here but not sure why

it is very imbalanced on the writes???  Is there a block size I should
change or something?

 

Once I get done with this, I want to write a map job to take data from
another db and stuff

It into my small little cluster to test it all out as a small prototype.

 

Thanks,

Dean
