Hello,
I am running a ycsb instance to insert data into hbase.All was well when
this was against hbase 0.96.1.Now I am trying to run the same program to
another cluster which is configured with hbase 0.98.4.I get the below
error on the client side.Could some one help me with this?.
The znode
Do you have replication turned on in hbase and if so is your slave
consuming the replicated data?.

Hello,
I have a field which is indexed and stored in the solr schema( 4.4.solr
cloud).This field is relatively huge and I plan to only index the field
and not to store.Is there a need to re-index the documents once this
change is made?.
Thanks,
Nishanth

You can use ycsb for this purpose.See here

HI,
We were running an hbase cluster with replication enabled.How ever we have
moved away from replication and turned this off.I also went ahead and
removed the peers from hbase shell.How ever the oldwals directory is not
cleaned up.I am using hbase version 0.96.1. Is it safe enough to delete
Hi All,
I am running a map reduce job which scans the hbase table for a particular
time period and then creates some files from that.The job runs fine for 10
minutes or so and few around 10% of maps get completed succesfully.Here is
the error that I am getting.Can some one help?

Hey folks,
I am trying to write a map reduce in pig against my hbase table.I have a
salting in my rowkey appended with reverse timestamps ,so I guess the best
way is to do a scan for all the dates that I require to pull out
records.Does any one know if pig supports hbase scan out of the box or

Hey folks,
How do I remove a dead region server?.I manually failed over the hbase
master but this is still appearing in master UI and also on the status
command that I run.
Thanks,

Can you telnet to port 2181 and 60020 on the remote cluster if you are
running default ports.I had a similar issue in the past where there was
firewall.

Hey folks,
I have been reading a bit about parque and how hive and impala works well
on data stored in parque format.Is it even possible to do the same with
hbase to reduce storage etc..

Hi Ted ,
Since I am also working on similar thing is there a way we can first test
the filter on client side?.You know what I mean without disrupting others
who are using the same cluster for other work?

Hey folks,
I am evaluating on loading an hbase table from parquet files based on
some rules that would be applied on parquet file records.Could some one
help me on what would be the best way to do this?.

Hi everyone,
This question may have been asked many times but I would really appreciate
if some one can help me on how to go about this.
Currently my hbase table consists of about 10 columns per row which in
total has an average size of 5K.The chunk of the size is held by one
particular col

Hey All,
I am sorry if this is a naive question.Do we need to generate a proto file
using proto buffer compiler when implementing a filter.I did not see that
any where in the documentation.Can some one help please?

Hi All,
I have an hbase table with multiple cfs (say c1,c2,c3).Each of this column
family has a column 'message' which is about 5K.What I need to do is to
grab only the first 1000 Characters of this message when I do a get on the
table using row Key.I was thinking of using filters to do this on
Also take a look at HBASE-5416 which introduced essential column family.

Hi everyone,
We have an hbase implementation where we have a single table which stores
different types of log messages.We have a requirement to notify (send
email to mailing list) when we receive a particular type of message.I will
be able to able to identify this type of message by looking a
39 matches
