Client-driven checksum verification not functioning
---------------------------------------------------
Key: HDFS-877
URL: https://issues.apache.org/jira/browse/HDFS-877
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 0.20.1, 0.21.0, 0.22.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
This is actually the reason for HDFS-734 (TestDatanodeBlockScanner timing out).
The issue is that DFSInputStream relies on readChunk being called one last time
at the end of the file in order to receive the lastPacketInBlock=true packet
from the DN. However, DFSInputStream.read checks pos < getFileLength() before
issuing the read. Thus gotEOS never shifts to true and checksumOk() is never
called.
