我们耗尽了测试hdfs集群上的所有可用空间，所以hbase崩溃了。在清理了一些空间之后，我们可以重新启动hbase，但是在启动之后，分布式日志剥离作业一直失败。作业如下所示：

Splitting log file hdfs://192.168.249.1:9000/hdfs/hbase/.logs/host-3,60020,1382113928374-splitting/host-3%2C60020%2C1382113928374.1382523937002 into a temporary staging area.

regionserver正在尝试租用该文件一段时间：

然后主机中止作业：

在我看来，问题是regionserver无法获得此文件的租约，因为它已经打开，所以我与 sudo -u hdfs hadoop fsck /hdfs/hbase/.logs/ -openforwrite ，并确认：

OPENFORWRITE: /hdfs/hbase/.logs/host-3,60020,1382113928374-splitting/host-3%2C60020%2C1382113928374.1382523937002 41274332 bytes, 1 block(s), OPENFORWRITE:

我试图关闭hbase，但文件保持打开状态以供写入。我怎样才能去掉这面旗帜？
