Hi,
if the namenode (or zookeeper) is down for some reason,
hbase-regionserver(on datanode) keep retrying to connect to zookeeper
continuously for long time.
We tried by setting "hbase.client.retries.number" to 1 in hbase-site.xml,
But no effect.
Can someone please let us know, hbase configurati
Hi,
We are planning to move our cluster from hbase 0.94.14 to 0.98.2.
Our query is -
If we have backup taken(using snapshots) on hbase 0.94.14, can we restore
the same backup on newer version of hbase 0.98.2?
Thanks

Hi,
Does new hbase version(>0.99) supports incremental backup using snapshots?
If not supported in current releases, is it planned to add in future
releases?
can we export snapshots to local file system directly?
Thanks

Hi ,
1) Where can we find hbase.098 tar
with hbase 0.98 directory structure similar to hbase-0.94.19 ?

Hi all,
We want to know if there is any option to remove duplicate data in Hbase
based on column family dynamically?

Hi,
we are taking tsdb data backup using HBase snapshots.
We tested the scenario as mentioned below:
1. Created snapshots and exported all snapshots successfully.
Exported data contains archive+hbase-snapshot
2. Started HBase from scratch (removed all Hbase tabled and created again)
3. Succe

Hi,
While exporting HBase snapshots we need to specify number of mappers to use
as mentioned below.To get better performance how many mappers can be used
and please let us know based on which parameters we need to decide on
number of mappers to use.I am new to HBase.
Please refer if there are go

Hi,
We have cluster with 4 data nodes and HBase version is 0.94.10.
We have created snapshot for all hbase tables and trying to export snapshot
in two ways.
option 1.Export snapshot into same cluster hdfs
hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot
hbase_tbl_snapshot_name
Hi ,
In order to take incremental backup using export of hbase , we followed
http://hbase.apache.org/book/ops_mgt.html#import
Few things that need clarification are :
1. what does version mean? is is the same version number which we give
during creation of hbase table ?
2. what if we don't sp
We want to use that exported data in case of any disaster happens.
Thanks

Hi,
can someone please let us know if we can export snapshots data directly to
outside of cluster without copying to local.
Please refer us if there are any blog with example.
Below command is copying data to local file system under /tmp.
hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -sn
Hi Matteo,
Thanks a lot for your quick and detailed explanation.

Hi,
We are using HBase 0.94.10 version.
We could able to take snapshots for all hbase tables and export into
another cluster successfully.
To take HBase table snapshots we followed procedure given at below apache
link.

Purpose of taking snapshots
HI ,
I would like to know if JRE alone is sufficient to run HBASE services or
JDK is required ?

When these nodes are back I use to get "WARN org.apache.hadoop.DFSClient:
