I recommend you to deploy master node of HDFS, MR, HBase in different
servers which can get better performance.
An example scenario is:
1, Deploy zookeeper on each server or the server1, server2, server3, and
they make up a zookeeper cluster of odd numbers.
2, Deploy HDFS NameNode, backup NN, MR
Hi,
I was just trawling HBase JIRA for this info after one happy user of SPM
for HBase asked if we could show read requests separately from write
requests.
See
https://issues.apache.org/jira/browse/HBASE-4989
https://issues.apache.org/jira/browse/HBASE-3647
There is also https://issues.apache.or
I think one possible reason is block caching. Have you turned the block caching
off during scanning?

I do advise you to use Cloudera Manager its a very simple and opensource
cluster configuration software..
A good design is to run zookeeper on node1, node2, another node alone

Hi,
I am a newbie to Hadoop, HBase and Hive. I installed Hadoop, HBase and Hive
in pseudodistributed mode and everything works fine. Now I am planning to
set up an simple Hadoop Cluster (5 nodes) with Hive, HBase and ZooKeeper.
I´ve read several documentations and instructions before but i could n
Oh! I see!
Super, thanks a lot for all this information! Very clear to me now!
Thanks,

may be because bulk load writes to the same region thus putting the entire
load on a single region server.

Thanks, for the suggestions. Will do instrumentation based on JMX.

Just a guess... have you done any compactions on the table post bulk load?

Regards, Amit.
Did you tuned the RegionServer where you has that data range hosted?
Why do you say that scans are slower after a bulk load?
Did you test it before bulk load?
HBase version?

So, question is.
On the RowCounter MapReduce we can pass
"-Dhbase.client.scanner.caching=100". But I'm not able to find

I only found that on the HTable and it's read from the configuration.

Hi,
I'm building a MapReduce and I have some question about the -D parameters.
I don't know if HBase shell scan command use ColumnCountGetFilter.
The absence of compaction could explain the 2 same cell displayed.
But when I filter on one colfam, I get only 1 cell ... from the wrong
colfam (like if the cell is stored in the wrong HFile) ...
When I add clone of my KeyValues in
The problem is caused by the code, as I create the configuration by
myself. The correct way is to use getConfiguration() method.
