Subject Re: exportSnapshot tool
Date Sun, 03 May 2015 15:00:56 GMT
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

Regards,
Akmal Abbasov
