Hello,

Is it possible to export table schema only versus exporting the entire
table?  I need this so I can create a separate table for QA purposes.

In shell, if you do 'describe TABLENAME', the output can be used
create the table IIRC.

Let us know if it doesn't work.

St.Ack

Rita,

I guess you are looking for something similar to RBDMS (say, oracle) is
providing.

If that is the case, Exporting table structure alone doesn’t make much sense
in HBase case as HBase table can contain unstructured data.
I mean, number of column qualifiers (Equivalent with Oracle columns) is not
fixed.

Otherwise, as Stack mentioned, you can use describe command output to
recreate a table (manually).
