Hopefully we can release 0.92 this month.
I am not aware of patch that back ports filter language to 0.90 branch.
Cheers

Hi Doug,
Thanks for update. By when we can expect release of Hbase 0.92.
Let me know if there are any patches available which I can apply in Hbase
0.90.3 to attain Filters via thrift.
Thanks

Hi I am trying to get HBase running in pseudo-distributed mode. It
appears to work when I use standalone mode but in pseudo distributed
mode I get:

Hello Lars,
Thanks for your previous help. Got a new question for you. I now have the
opportunity to try using Hadoop and HBase on a newly installed cluster here, at
a nominal cost. A lot of compute power (480+ nodes, 16 cores per node going up
to 32 by the end of FY12, 64 GB RAM per node, wit
Shame on me. In my haste and excitement to upgrade to the latest version
of hbase I forgot to update the client jar.

Gaojinchao,
I'm not certain, but this looks a lot like some of the issues I've been dealing
with lately (namely, non-Java-heap memory leakage).
First, -XX:MaxDirectMemorySize doesn't seem to be a solution. This flag is
poorly documented, and moreover the problem appears to be related to

Hey Shawn,
Run it as:
HADOOP_CLASSPATH=`hbase classpath` hadoop jar (…)
The guava supplied class is required on the frontend code as well, which is
what it fails to find and hence crashes out with a no-class-def. Doing the
above should solve it for you.

Hello,
I am trying to do a bulk import of some data into a table (named TRANS)
with the following syntax:
hadoop jar /usr/lib/hbase/hbase-0.90.1-CDH3B4.jar importtsv -libjars
/usr/lib/hbase/lib/guava-r06.jar '-Dimporttsv.separator=,'
-Dimporttsv.columns=CF1:TBC2,CF1:TBC1,HBASE_ROW_KEY TRANS
/
Scenario:
- regionserver machine was rebooted . AWS random reboot .
Regionserver logs show shutdown
- Datanode which is on same machine also recvd a kill command
- Master did not migrate the regions. It did detect the node down
- I checked after 6 hours , the hbase was in inconsistent

1) Does having dfs.replication factor "3" in general result in table data
size of 3x + y (where x is the size of the file in local file system and y
is some additional space for meta information storage) ???
2) Does Hbase, pre allocate space for all the cell versions when the cell
is created for t
Wow, that is almost a guide for the rest of us. You missed only the logs.
Going through your steps, these are all I note:
1. Why use CDH3u1 when u2 is the latest?
2. You do not need 3 ZKs on a single machine. One is sufficient - you've only
ended up complicating the setup there :)
3. The prop "hb

This piece of code can be eliminated if you only apply the coprocessor
to one table,
I am trying to install hbase on my local system ubutnu 11.04 .
what i have done to do that is :
1. SSH Configuration
1. sh-keygen -t rsa
2. do the enter enter when it ask something.
3. cd ~/.ssh
4. sudo apt-get install openssh-server
5. ssh localhost
2. Install
Ok. But can some1 explain why the data size is exploding the way I have
mentioned earlier.
I have tried to insert sample data of arnd 12GB. The data occupied by Hbase
table is arnd 130GB. All my columns i.e. including the ROWID are strings. I
have even tried converting by ROWID to long, but that s
the point, I refer to is not so much about when hbase's server side
flushes, but when the client side flushes.
If you put every value immediately, it will result every time in an RPC
call. If you collect the data on the client side and flush (on the client
side) manually, it will result in one RPC
I believe that these filters...

... were added to .92. This should be marked as such in the book. I'll
update it.

Hi all,
I have some query related to combining multiple queries in Hbase.
I want my data to be stored in decreasing order i.e latest entry should appear
first in Hbase:

Any body any hints ?
Doesn't the configuration setting "hbase.hregion.memstore.flush.size" do
the bulk insert ??? I was of the opinion that Hbase would flush all the
puts to the disk when it's memstore is filled, whose property is defined in
hbase-default.xml. Is my understanding wrong here ???
