exportSnapshot tool
Hi,
I using exportSnapshot tool, and observed a strange behaviour. I have HBase HA configured in my destination cluster. I have hbm1 and hbm2 which are HBase masters.
Currently hbm2 is active, and hbm1 is in standby mode. I am assuming that when I am using exportSnapshot tool I need to specify the address of the server where my active Hbase master is running.
But, when I do this, I am getting

Re:Re: exportSnapshot tool
Posted by David chen <c7...@163.com>.
Your active namenode and hbase master share on a host? If so, it's okay.
I don't think your configuration is problematic, the error you posted should be related with HDFS HA, but not HBase HA.
I ever encountered the error, but there were both standby namenode in my current scenario. The error was solved by the way to initialize the HDFS HA state in ZooKeeper, so, i suggest you can attempt the way.

Hi David,
I have HDFS HA. I was supposing that maybe the namenode with an active hbase master is not active. But no, both namenode and hbase master are active in hb1m.
So is it supposed to work in that way, or it is a problem with my configurations?
Thank you.

Hi Ted,
Yes, I can confirm that hb1m is active
I tested it using ./hbase-jruby get-active-master.rb which is in HBASE_DIR/bin/
And also I can see that hb1m is an active one from my dashboard.
Thank you.

bq. Operation category READ is not supported in state standby
Can you confirm whether active namenode is running on hb1m ?

Hi Ted,
I am using hadoop-2.5.1 and hbase-0.98.7-hadoop2.
The command for snapshot export is:
hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot snappy -copy-to hdfs://hb1m/hbase -overwrite
Thank you

Re: exportSnapshot tool
Posted by Ted Yu <yu...@gmail.com>.
Can you give us a bit more information ?
Such as:
release of hbase you're using
release of hadoop you're using
the command line for snapshot export
Thanks
