> Project: Hadoop HDFS
> Issue Type: Bug
> Components: data-node

>
> The junit test failed when iterates a number of times with larger chunk size
> on Linux. Once a while, the visible number of bytes seen by a reader is
> slightly less than what was supposed to be.
> When run with the following parameter, it failed more often on Linux ( as
> reported by John George) than my Mac:
> private static final int WR_NTIMES = 300;
> private static final int WR_CHUNK_SIZE = 10000;
> Adding more debugging output to the source, this is a sample of the output:
> Caused by: java.io.IOException: readData mismatch in byte read:
> expected=2770000 ; got 2765312
> at
> org.apache.hadoop.hdfs.TestWriteRead.readData(TestWriteRead.java:141)
