hi Mohammad Tariq,
thanks for reply.
I follow your instruction, change the hosts to this:
master:
127.0.0.1 localhost 127.0.0.1 localhost ubuntu 10.66.201.243 master
10.66.201.244 slave1 10.66.201.245 slave2
slave1:
127.0.0.1 localhost 127.0.0.1 slave1 ubuntu 10.66.201.243 master 10.66.201.2
Hi exp,
Do not remove this line, instead make it 127.0.0.1..and copy the
hadoop-core-0.20.204.0.jar from your HADOOP_HOME and
commons-configuration-1.6.jar from the HADOOP_HOME/lib folder to the
HBASE_HOME/lib folder. It should work then..Please let me know if it
works for you.

Hi stuti,
i found the same problem, so i thought of the solution is, i added
zookeeper-3.3.2.jar and log4j-1.2.5.jar on classpath of HBASE. it worked
fine.
thank you stuti.
While executing one more program on mapreduce i am getting following error

some disks of one node in my hbase cluster were broken, and after I mounted

Steve,
We have been using timeouts in production via two different methods:
1. Use RPC timeout mechanism provided by HBase client. For this you will
need both 2937 and 3154. We backported 2937 to 0.90.3. The reason 3154
alone does not help is because if you set the conf parameter introduced in

Can u try w/o a limit or with upped limit and see if a diff?Sounds
plausible yes but looks like u could make a fact with some small experiments

Hi,
I'm trying to understand what timeout controls are available in the hbase
client. I'm using hbase version 0.90.4-cdh3u2. I have a client application

client side timeout such that the client can clean-up in a case w

I'm tight on time... Short answer...
Strip out the xml in to some object and then consider using Avro to write the
object to HBase.
This could probably shrink your footprint per record/row.

How big are these XML files?
You might want to consider storing them in HDFS directly and only Meta

Hi,
A few notes:
Remove the 127.0.1.1 lines, they usually mess things up.
The hbase.master configuration has been removed from the HBase code
more than 2 years ago, you can remove it too.

Thanks for the reply.
But that is from Java ..I am looking from the HBase shell?

Hi Mohammad,
It sounds like you want to implement a hierarchial data model within HBase. You
can do this, albeit there are some drawbacks...
In terms of drawbacks...
The best example that I can think of is implementing a point of sale solution

Hello list,
I want to store xml files in Hbase and these files may have

In our tests, filtering rows with timestamps was much faster than using
a filter which results in a full table scan. But, I question the
reliability to use the internal timestamp to detect new data and if this
still scales with a growing amount of data over the years.
