Konstantin Shvachko commented on HDFS-2498:
-------------------------------------------

See the following assert in the logs when the test actually succeeded:
{code}
Exception in thread "ReadWorker-7-/TestParallelRead.dat.0" java.lang.AssertionError: Bad args: 262098 + 46 should be < 262144
	at org.junit.Assert.fail(Assert.java:91)
	at org.junit.Assert.assertTrue(Assert.java:43)
	at org.apache.hadoop.hdfs.TestParallelRead$ReadWorker.read(TestParallelRead.java:137)
	at org.apache.hadoop.hdfs.TestParallelRead$ReadWorker.run(TestParallelRead.java:104)
{code}

This is a wrong condition, should be <=
