Ted Yu updated HBASE-8465:
--------------------------
Description:
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
{code}'-for-rollback-'{code}). 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.
