So you want one version with ts= give ts?
Have a look at Scan#setTimeRange(long minStamp, long maxStamp)
If you know the exact ts for cells, you can use Scan#setTimeStamp(long
timestamp)

Hi,
Is there a way to detect which version of HBase one is running?
Is there an API for that, or a constant with this value, or maybe an MBean
or some other way to get to this info?
Thanks,

Yes, you can use the org.apache.hadoop.hbase.util.VersionInfo class.
From java code, you can use VersionInfo.getVersion(). From shell
scripts, you can just run hbase version and parse the output.

Otis:
You can parse the output from status 'detailed' command - look for the
line starting with 'version'
I checked the output from /jmx but didn't find such information there. The
version would appear in the classpath but that's not easy to parse.
One note about hbase version is that it returns

As always, food and beverages are being provided. Come and hear about

Java-wise, you can use this API in HBaseAdmin:
ClusterStatus getClusterStatus() throws IOException;
ClusterStatus provides:
public String getHBaseVersion() {

Hi,
Thanks Gary, I think this is exactly what I was after!
Btw. might be nice to expose this via JMX, too, for apps who needs this
info but are not in process.

Hi
I'm creating my first HBase application and I'm trying to connect from the
Java application in my Java IDE to my HBase server on a Horton Workds 2.1
Virtual Machine. When I run I get:

Does this mean that I have to have hadoop

Yes I already applied that.
I just wanted to understand that if I have a web application then I'll have
to have the hadoop distribution installed to use the hbase client.

Thank you Andrew, this is an excellent answer, I get it now. I will try your

Hi,
I'm currently saving JSON in pure String format in the value cell and
depends on HBase' block compression to reduce the overhead of JSON.
I'm wondering if there's a more space efficient way to store JSON?
(there're lots of 0s and 1s, JSON String actually is an OK format)
I want to keep the
There is FASTDIFF data block encoding.

I thought FASTDIFF was only for rowkey and columns, great if it also works
in value cell.
And thanks for the bjson link!

Hi
Since I'm storing
historical data (snapshot data) and changes between adjacent value cells
are relatively small.
If the values are changing even if it is smaller the FASTDIFF will rewrite
the value part. Only if there are exact matches then it would skip the
value part. JFYI.
