hope it helps. this is what I do on apache hadoop 1.0.x and hbase 0.92.y:
in hbase-site.xml add:
hbase.regionserver.codecs
snappy
copy that file into the hadoop conf directory.
in hbase-env.sh:
export HBASE_LIBRARY_PATH=/pathtoyourhadoop/lib/native/Linux-amd64-64
( In hbase-env.sh I set also
Hey,
Which version of Hadoop are you using? I wasn't able to enable snappy
compression with hadoop 1.0.1 had to move to 1.0.3.

Hi Jean
Incase of Puts and Scans if the split is in progress it will retry.
Suppose before the client gets to know about the split, still if the put
is directed with the parent region row key, internally HBase directs it to
the correct daughter region.
But i am not clear in what you mean by Regio
Ok. so if on the client side I'm "simply" using Puts, scans and gets
fron the HTableInterface, I don't have to worry about that since it
will retry.
But I still should consider catching exceptions when regions are not
available because the region server is down for less than 3 minutes,
right?

Hi,
In $HBASE_HOME/conf/hbase-env.sh, have you added the following line? (assume
that you are using 64-bit)
export HBASE_LIBRARY_PATH=/usr/lib/hadoop/lib/native/Linux-amd64-64
If yes, I guess you should try to restart HBase.
Thanks

It's not accessible, but it's more or less transparent (latency impact
aside) for the end user: the hbase client will retry the operation.

Hi,
When a region is moving or splitting, is it still accessible? Or the
region is offline until the operation ends?
Thanks,

Hi Anoop,
Can you give me a more detailed information about how can I take a
look at RS threads doing?
Thanks!

Hi I am using YCSB to measure the performance of some complex Get/Scan,
i.e., with some filters. I found that I got weird high latency from YCSB
client but both HBase server and YCSB client are NOT saturated (in terms
of network, I/O, CPU). So I want to measure the server time a single
Get/Scan
So. I spent few hours on that yesterday with no luck.
Here is what I did:
- Install the google tar, untared, configured, maked and installed it.
- Copied the .so files all over my fs in the os lib dir,
HBase/lib/native and subdirs, Hadoop/lib/native and subdirs.
- Installed all debian packages wit
