"IOException: No space left on device" is handled incorrectly
-------------------------------------------------------------
Key: HADOOP-324
URL: http://issues.apache.org/jira/browse/HADOOP-324
Project: Hadoop
Type: Bug
Versions: 0.3.2
Reporter: Konstantin Shvachko
When a data node disk is almost full the name node still assigns blocks to the
data node.
By the time the data node actually tries to write that data to disk the disk
may become full.
Current implementation forces the data node to shutdown after that.
The expected behavior is to report the block write failure and continue.
The Exception looks as follows:
java.io.IOException: No space left on device

at java.io.FileOutputStream.write(FileOutputStream.java:260)
at java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java:65)
