Hi,
We need to enable replication on a live cluster. However it requires
disabling the table and bringing the required column families under the
scope of replication as under.
disable 'your_table'
alter 'your_table', {NAME = 'family_name', REPLICATION_SCOPE = '1'}
enable 'your_table'
This is
I am running mapreduce job to insert the data into HBase, Map phase is
running fine, but when the reducer starts it fails on all nodes except one
node and i notice below error on failed tasks. Out of 12 tasktrackers, one
tasktracker can connect to HBase and insert the data. Class path is set on
Which HBase release are you using ?
Mind showing us how you initialize the reduce tasks ?
Cheers

I am using HBase 94.6, i am not pretty sure about how we intialize
reducers. I can ask my developer regarding that.
Is there any other issue that can cause reduce task not connecting to
HBase? I Set only 1 reducer to this job, it succeeds only if that reducer
task is assigned to one of the
You could always set hbase.online.schema.update.enable to true on your
master, restart it (but not the cluster), and you could do what you
are describing... but it's a risky feature to use before 0.96.0.
Did you also set hbase.replication to true? If not, you'll have to do
it on the region
More information from the developer would help.
Also take a look at TableMapReduceUtil#initTableReducerJob() and how it is
used in 0.94 code base.
Cheers

Thanks for the reply JD! I came to know about this online schema setting
shortly after I made the post.
And yes ,I know the hbase.replication needs to be kept set to true. However
enabling that on a live cluster is not an issue for as we can do that
incrementally one region server at a time after
Hi hbase users,
We got an issue when import data from thrift (perl)
We found the number of data is less than expected.
when scan the table, we got:
ERROR: java.lang.RuntimeException:
org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed after
attempts=7, exceptions:

Which HBase release are you using ?
Was it possible that the import included Delete's ?
Cheers
