Admin.takeSnapshotAsync介绍

[英]Take a snapshot without waiting for the server to complete that snapshot (asynchronous) Only a single snapshot should be taken at a time, or results may be undefined.
[中]在不等待服务器完成快照的情况下拍摄快照（异步）一次只能拍摄一个快照，否则结果可能未定义。

@Test
public void testAsyncFlushSnapshot() throws Exception {
 SnapshotProtos.SnapshotDescription snapshot = SnapshotProtos.SnapshotDescription.newBuilder()
   .setName("asyncSnapshot").setTable(TABLE_NAME.getNameAsString())
   .setType(SnapshotProtos.SnapshotDescription.Type.FLUSH).build();
 // take the snapshot async
 admin.takeSnapshotAsync(
  new SnapshotDescription("asyncSnapshot", TABLE_NAME, SnapshotType.FLUSH));
 // constantly loop, looking for the snapshot to complete
 HMaster master = UTIL.getMiniHBaseCluster().getMaster();
 SnapshotTestingUtils.waitForSnapshotToComplete(master, snapshot, 200);
 LOG.info(" === Async Snapshot Completed ===");
 UTIL.getHBaseCluster().getMaster().getMasterFileSystem().logFileSystemState(LOG);
 // make sure we get the snapshot
 SnapshotTestingUtils.assertOneSnapshotThatMatches(admin, snapshot);
}
