Jing Zhao commented on HDFS-8481:
---------------------------------
While debugging HDFS-8319, I just found that in
{{TestWriteReadStripedFile#testWritePreadWithDNFailure}}, if we change the
startOffsetInFile from cellSize * 5 to 0, the test fails with the following
error msg:
{code}
java.lang.AssertionError: Byte at 524288 should be the same expected:<27> but
was:<-9>
at org.junit.Assert.fail(Assert.java:88)
at org.junit.Assert.failNotEquals(Assert.java:743)
at org.junit.Assert.assertEquals(Assert.java:118)
at org.junit.Assert.assertEquals(Assert.java:555)
at
org.apache.hadoop.hdfs.TestWriteReadStripedFile.testWritePreadWithDNFailure(TestWriteReadStripedFile.java:390)
{code}
[~zhz] and [~drankye], is it possible that this is caused by some issue with
decoder?
