I am using hadoop 0.20.1. So hdfs-265 cannot be applied to it?
hmmmm.

No I haven't applied them yet. Can you specify the patches other
than HDFS-200.

Someone holds the lease on the file you are trying to open?
You mention scribe. Do you have hdfs-200 and friends applied to your
cluster?

What hadoop version are you running? hdfs-265 won't apply to hadoop
0.20.x if that is what you are running.
