Takanobu Asanuma updated HDFS-12677:
------------------------------------
Attachment: HDFS-12677.1.patch
Uploaded the 1st patch. The new test class with a random ec policy extends
{{TestReconstructStripedFile}} with a few changes.
When the ec policy is {{XOR-2-1-1024k}}, this assertion fails.
{code:title=TestReconstructStripedFile#testNNSendsErasureCodingTasks|borderStyle=solid}
assertTrue(policy.getNumParityUnits() >= deadDN);
{code}
I checked the code and this assertion seems not to make sense. So the 1st patch
removes it. I confirmed that all EC policies pass the all tests with the patch
in my local computer.
