我想知道我是否可以使用hbase快照输出进行批量加载？ 我正在尝试将数据加载到另一个集群中，而org.apache.hadoop.hbase.snapshot.ExportSnapshot对我来说并不起作用，因为我们有超过1Tb的数据需要传输。
所以我在看Snapshots，看起来创建和导出快照会创建hfiles吗？
hbase org.apache.hadoop.hbase.snapshot.SnapshotInfo -snapshot metadata_20150424 -files
2015-05-01 19:41:48,313 INFO [main] Configuration.deprecation: hadoop.native.lib is deprecated. Instead, use io.native.lib.available

我能够在本地导出文件，然后将它们导入我的其他群集。
将快照导出到本地hdfs后，文件如下所示：

在我导出文件的群集上，它们如下所示：

然后我想我可以运行LoadIncrementalHFiles实用程序：
bin/hbase org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles /import/metadata_snapshot/metadata_20150424/ metadata
但是，我收到以下错误。

我不确定我所做的事情是否可能，但我想我会尝试它，因为导入/导出实用程序对我不起作用。有谁知道这是否可能，如果是的话，我做错了什么？
提前感谢！
