sam rash commented on HDFS-1102:
--------------------------------
proposed solution:
StreamFile: Datanode will set the content length in the header
HftpInputStream: read() method will verify that when underlying input stream
from the http connection returns -1 that it has all the bytes, else throws an
EOFException
> HftpFileSystem : errors during transfer result in truncated transfer

> Key: HDFS-1102
> URL: https://issues.apache.org/jira/browse/HDFS-1102
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: data-node, hdfs client
> Affects Versions: 0.20.1
> Reporter: sam rash
>
> If an error occurs transferring the data over HTTP, the HftpInputStream does
> not know it received fewer bytes than the file contains. We can at least
> detect this and throw an EOFException when this occurs.
