I try to backup hbase is a brute force, yet a faster method by copying
everything under the adoop.tmp.dir which includes the namenode, data
etc. That is, I
1) shut down Hbase
2) shout down Hadoo
3 ) copy everything under hadoop.tmp.dir (/mnt.hadoop in my case) to a
temp directory
I'm doing that for the Master and the Slaves
4) I then copy the temp directory to the .tmp.dir (/mnt.hadoop in my
case) . Master is copied to Master and the same for the slaves (I
verified the copy is successful ).
5) launch Hadoo
6) Launch Hbase
But the tables and data I created on Hbase are now gone.
Can I use this method to backup, is there anything else I should backup
?
Thanks
