when I try to backup and restore the cube's hbase table as the following
familiar commands:
1, sudo -uhbase hbase org.apache.hadoop.hbase.mapreduce.Export tmember
/backup/projects/channel/tmember
2, hadoop fs -copyToLocal -crc /backup/projects/channel/tmember
/home/olap/scripts/cluster_mgr/test/tmember
3, sudo -uhbase hadoop fs -rm -r /backup/projects/channel/tmember
4, in hbase shell, disable table and drop table tmemeber
5, sudo -uhbase hadoop fs -copyFromLocal
/home/olap/scripts/cluster_mgr/test/tmember /backup/projects/channel/tmember
6, sudo -uhbase hbase org.apache.hadoop.hbase.mapreduce.Import tmember
/backup/projects/channel/tmember
the first 5 steps work OK, when step 6, it always throws error like the
following, no more information in hbase log

finally, I found that if I create a empty hbase table named tmember first
before step 6, then step 6 works successfully, however, how can we create
such a empty table or how to know the "create table" statement just like
"show create table" in mysql?
