Subject [jira] [Created] (HBASE-8465) Improvement for snapshot restore
Date Tue, 30 Apr 2013 09:04:16 GMT
Ted Yu created HBASE-8465:
-----------------------------

             Summary: Improvement for snapshot restore
                 Key: HBASE-8465
                 URL: https://issues.apache.org/jira/browse/HBASE-8465
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu
            Assignee: Ted Yu


Below is an excerpt from snapshot restore javadoc:
{code}
   * Restore the specified snapshot on the original table. (The table must be disabled)
   * Before restoring the table, a new snapshot with the current table state is created.
   * In case of failure, the table will be rolled back to the its original state.
{code}
We can improve the handling of rollbackSnapshot in two ways:

1. give better name to the rollbackSnapshot (adding '-for-rollback-'). Currently the name
is of the form:
    String rollbackSnapshot = snapshotName + "-" + EnvironmentEdgeManager.currentTimeMillis();

2. drop rollbackSnapshot at the end of restoreSnapshot() if the restore is successful. We
can introduce new config param, named 'hbase.snapshot.restore.drop.rollback', to keep compatibility
with current behavior.
