copy table AND descriptor

Hi I have a table in cluster 1 with quite lengthy metadata (aka, 
descriptor). How can I replicate the data as well as descriptor to another 
table?
CopyTable, Export/Import does not handle table descriptor.

Thanks,
Wei

Hi Ted, Thanks for your remind. I made it in two steps:

1. write a java problem to create a table using original table's 
descriptor.
2. use ./bin/hbase org.apache.hadoop.hbase.mapreduce.CopyTable to copy the 
data

Best Regards,
Wei

Which version of HBase are you using ?

Have you tried using 'describe' shell command ?

Thanks
