Todd Lipcon commented on HDFS-1024:
-----------------------------------
Does the servlet not set a Content-length HTTP header? Since we're using HTTP
we might as well include it there. Then the HTTP client can easily verify it
without having to modify CheckpointSignature
> SecondaryNamenode fails to checkpoint because namenode fails with
> CancelledKeyException

> The secondary namenode fails to retrieve the entire fsimage from the

> the entire fsimage file and proceeds ahead with the checkpointing. Stack
> traces will be attached below.
