Jim Kellerman updated HBASE-1155:
---------------------------------
Attachment: patch.txt
Patch that uses new API's to recover file lease and read from last log file
being written by region server.
It does work, but slowly. As noted in HADOOP-4379, it takes almost an hour to
recover the file lease when the clusters are loaded.

> In order to guarantee that an HLog sync() flushes the data to the HDFS, we
> will need to invoke FSDataOutputStream.sync() per HADOOP-4379.
> Currently, there is no access to the underlying FSDataOutputStream from
> SequenceFile.Writer, as it is a package private member.
