Subject Re: The lease hard limit is 1 hour and in another client want to append to a file need to wait for 1 hour?

Hi Yanbo,

Clients can request a quicker lease recovery, via
DistributedFileSystem.recoverLease(Path f), as seen at
http://svn.apache.org/viewvc/hadoop/common/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/DistributedFileSystem.java?view=markup
(Line 236~). This is what HBase relies on when trying to open WAL
files for recovery.

Does this help?
