Re: EC2 Elastic MapReduce HBase install recommendations

2013-05-11 Thread Pal Konyves
Hi,

I decided not to make any tuning, because my whole project is about
experimenting with HBase (it's a scool project). However it turned out that
my sample data generated lots of rowkey collisions. 4 million inserts only
resulted in about 5000 rows. The data were different though in the columns.
When I changed my sample dataset to have no collisions in the rowkey, the
performance increased with a magnitude of 10. Why is that?

Thanks,
Pal

 You need to do this on startup of EMR cluster though...

High collision rate means high contention at taking the row locks. 
This results in poor write performance.

Re: EC2 Elastic MapReduce HBase install recommendations

2013-05-08 Thread Amandeep Khurana
To add to what Andy said - the key to getting HBase running well in AWS is:

1. Choose the right instance types. I usually recommend the HPC
instances or now the high storage density instances. Those will give
you the best performance.

2. Use the latest Amzn Linux AMIs and the latest HBase and HDFS
versions that work with each other.

3. Tune HBase for your workload. This you have to do anyway but HBase
on AWS is less forgiving as compared on on premise.

I've personally tested upto 10k req/sec/server writing 1K payloads on
HBase 0.92 (that's old!) on HPC instances.

Re: EC2 Elastic MapReduce HBase install recommendations

With respect to EMR, you can run HBase fairly easily.
You can't run MapR w HBase on EMR stick w Amazon's release.

And you can run it but you will want to know your tuning parameters up front 
when you instantiate it.

 M7 is not Apache HBase, or any HBase. It is a proprietary NoSQL datastore

 As for running HBase on EC2, we recently discussed some particulars, see
 the latter part of this thread: http://search-hadoop.com/m/rI1HpK90gu where
 I hijack it. I wouldn't recommend launching HBase as part of an EMR flow
 unless you want to use it only for temporary random access storage, and in
 which case use m2.2xlarge/m2.4xlarge instance types. Otherwise, set up a
 dedicated HBase backed storage service on high I/O instance types. The
 fundamental issue is IO performance on the EC2 platform is fair to poor.
 
 I have also noticed a large difference in baseline block device latency if
 using an old Amazon Linux AMI ( 2013) or the latest AMIs from this year.
 Use the new ones, they cut the latency long tail in half. There were some
 significant kernel level improvements I gather.

 Hi,
 
 Has anyone got some recommendations about running HBase on EC2? I am
 testing it, and so far I am very disappointed with it. I did not change
 anything about the default 'Amazon distribution' installation. It has one
 MasterNode and two slave nodes, and write performance is around 2500
 small
 rows per sec at most, but I expected it to be way  better. Oh, and this
 is
 with batch put operations with autocommit turned off, where each batch
 containes about 500-1000 rows... When I do it with autocommit, it does
 not
 even reach the 1000 rows per sec.

I think that Andrew talked about this some years ago and he created some
scripts for that. You can find them here:
https://github.com/apurtell/hbase-ec2

Then, you can review some links about this topic:

Your EC2 instance is having EBS or instance type as the data store?
If it is EBS then the latency is bit high and this is as per Andrew's
experience.
