> Hit a fsimage download problem:
> Client tries to download fsimage, and got:
> WARN org.apache.hadoop.security.UserGroupInformation:
> PriviledgedActionException as:hdfs (auth:SIMPLE) cause:java.io.IOException:
> File http://x.y.z:50070/imagetransfer?getimage=1&txid=latest received length
> xyz is not of the advertised size abc.
> Basically client does not get enough fsimage data and finished prematurely
> without any exception thrown, until it finds the size of data received is
> smaller than expected. The client then closed the conenction to NN, that
> caused NN to report
> INFO org.apache.hadoop.hdfs.server.namenode.TransferFsImage: Connection
> closed by client
> This jira is to add some more information in logs to help debugging the
> sitaution. Specifically, report the stack trace when the connection is
> closed. And how much data has been sent at that point. etc.
