Ted Yu commented on HBASE-8465: ------------------------------- {code} + failSafeSnapshotSnapshotName = conf.get("hbase.snapshot.restore.failsafe.name", + "hbase-restore-failsafe-{table.name}-{restore.timestamp}"); {code} The failsafe snapshot name is pretty long. Can it include the snapshotName for the restore operation ? {code} + String msg = "Restore snapshot=" + snapshotName + + " failed. Rollback to snapshot=" + failSafeSnapshotSnapshotName + " succeeded."; + LOG.error(msg, e); + internalRestoreSnapshot(failSafeSnapshotSnapshotName, tableName); {code} The success message seems to come a bit early. > Auto-drop rollback snapshot 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 > Fix For: 0.98.0, 0.96.1 > > Attachments: 8465-trunk-v1.txt, 8465-trunk-v2.txt, HBASE-8465-v3.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.1#6144)
