Log onto the server where regionserver process is running and issue:
ps aux | grep regionserver
In the output look for '-Dhbase.log.dir=' which would tell you the location
of the log.

Hi,
I'd like to do some benchmarks fo HBase but I don't know what tool
could use. I started to make some code but I guess that there're some
easier.
I've taken a look to JMeter, but I guess that I'd attack directly from
Java, JMeter looks great but I don't know if it fits well in this
scenario.
Guillermo:
If you use hbase 0.98.x, please consider Andrew's ycsb repo:

I was checking that web, do you know if there's another possibility
since last updated for Cassandra was two years ago and I'd like to
compare bothof them with kind of same tool/code.

we have a standalone java code, which simply tries to insert one record
into an existing hbase table.
here it got the following error:but it is able to proceed. so this means
the following operation which triggered the error is useless ??? if so,
shouldn't the useless code be removed?
thanks
Is namenode running on my-hbase-master.com
http://my-hbase-master.com:8020/apps/hbase/data/lib ?
Which hbase release are you using ?
I assume hbase-site.xml is in the classpath of your app. What's the value
for hbase.rootdir ?

Thanks everyone for the feedback. What we ended up implementing is
something that does these merges programmatically, but limits merges to
regions that live on the same RS. They take on the order of just a few
seconds for us.

Maybe ask on Cassandra mailing list for the benchmark tool they use ?

I can find the hbase version from hbase shell (please see below):
hbase(main):001:0 version
0.98.1-cdh5.1.3, rUnknown, Tue Sep 16 20:19:34 PDT 2014
But where I can find my HBase region server log? I used all default option
when installing HBase, including all configurations.
Thanks for your
Is the HBase version is reliable solution to use in critical data. In case I
am not going to store duplicate data (same row key and time stamp).

In the /var/log/hbase folder, I can find two files:
1. hbase-cmf-hbase-HBASERESTSERVER-ip-172-x-x-x.ec2.internal.log.out
2. hbase-cmf-hbase-MASTER-ip-172-x-x-x.ec2.internal.log.out
The '1' file was updated several days before, so it won't help.
The '2' file only records the hbase log when I use
I am also working with a very similar project.
I tried two version for time-series data:
1. use id-timestamp as rowkey:
It's good for loading new inputs and also good for search. But bad for
the storage and slow when doing aggregation.
2. use id as rowkey and use array string for time and
Can you provide a bit more detail on your use case ?
If row key and timestamp are different across writes, there would be 1
version.

Have you looked a the default /var/log directory to see what you have there?
