Hi Anil,
Yes, I'm sure I'm running cluster in distributed mode (I see 21 parallel
map tasks in job tracker and processes on each node). max map tasks set to
7 for each node.
I run my job with the same cluster configuration on two tables:
1. Table located only on 1 node (I see it on HBase master
Hi Anil,
Yes, the second table is distributed, the first is not and I have 3х better
results for nondistrubuted table.
I use distributed hadoop mode for all cases.
Thanks.

Hi Alexander,
Is data properly distributed
Hi Alexander,
If you can provide more details of the stuff you are doing then it would be
helpful. Are you sure that your cluster is running in distributed mode? Did
you ran the job with 1 node in cluster and then added 2 additional node to
the same cluster?
Thanks,
Anil

Hello,
I'm running 3 data node cluster (8core Xeon, 16G) + 1 node for jobtracker
and namenode with Hadoop and HBase and have strange performance results.
The same map job runs with speed about 300 000 records per second for 1
node table and 100 000 records per second for table distributed to 3
Hi Alexander,
Is data properly distributed over the cluster in Distributed Mode? If the
data is not then you wont get good results in distributed mode.
Thanks,
Anil Gupta
