> Key: HBASE-8798
> URL: https://issues.apache.org/jira/browse/HBASE-8798
> Project: HBase
> Issue Type: Bug
> Components: shell, snapshots
> Affects Versions: 0.94.8, 0.95.1
> Reporter: Jerry He
> Assignee: Ted Yu
> Priority: Minor
> Fix For: 0.98.0
>
> Attachments: 8798-trunk-v2.txt, 8798-v3.txt, HBASE-8798-trunk.patch

> In HBase shell, the syntax for clone_snapshot is:
> hbase> clone_snapshot 'snapshotName', 'tableName'
> If the target table already exists, we'll get an error.
> For example:
> ------------------
> hbase(main):011:0> clone_snapshot 'mysnapshot1', 'TestTable'
> ERROR: Table already exists: mysnapshot1!
> Here is some help for this command:
> Create a new table by cloning the snapshot content.
> There're no copies of data involved.
> And writing on the newly created table will not influence the snapshot data.
> Examples:
> hbase> clone_snapshot 'snapshotName', 'tableName'
> ----------------------
> The bug is in the ERROR message:
> *ERROR: Table already exists: mysnapshot1!*
> We should output the table name, not the snapshot name.
> Currently, in command.rb, we have the output fixed as args.first for
> TableExistsException:
> {code}
> def translate_hbase_exceptions(*args)
> yield
> rescue org.apache.hadoop.hbase.exceptions.TableNotFoundException
> raise "Unknown table #{args.first}!"
> rescue org.apache.hadoop.hbase.exceptions.NoSuchColumnFamilyException
> valid_cols = table(args.first).get_all_columns.map { |c| c + '*' }
> raise "Unknown column family! Valid column names:
> #{valid_cols.join(", ")}"
> rescue org.apache.hadoop.hbase.exceptions.TableExistsException
> raise "Table already exists: #{args.first}!"
> end
> {code}
> This is fine with commands like 'create tableName ...' but not
> 'clone_snapshot snapshotName tableName'.
