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
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
, if
your cluster is starting up. If not, try running the OfflineMetaRepair
tool. Also, visit the master and region server logs for more information.

cluster into my backup/slave cluster,based on some application specific
policy.In other words I want to suppress replication of certain mutation
events, and allow the same only for the rest.

Hi,
I've a standalone Hbase cluster configured in a distributed mode (i.e. the
ZK, Master and the RegServer all running in separate JVMs on the same host).
The HBase master doesn't seem to be intializing successfully. This has
started happening since I encountered the stop-hbase script going
Thanks for clarifying the usage part out Stack!
As for programmatic monitoring, I was trying to figure out how to extend the
already available metrics capture mechanism (available for Region server and
Master server processes) to dump some *custom *metrics into a file (using

Thanks for that link Otis! This indeed allows completely overriding the
default monitoring by Hbase, however what we are looking at really is
capturing some additional metrics over and above what the monitoring is
already generating.
So, we figured a way to achieve that through co-processors as
