This distribution includes cryptographic software.  The country in 
which you currently reside may have restrictions on the import, 
possession, use, and/or re-export to another country, of 
encryption software.  BEFORE using any encryption software, please 
check your country's laws, regulations and policies concerning the
import, possession, or use, and re-export of encryption software, to 
see if this is permitted.  See <http://www.wassenaar.org/> for more
information.

The U.S. Government Department of Commerce, Bureau of Industry and
Security (BIS), has classified this software as Export Commodity 
Control Number (ECCN) 5D002.C.1, which includes information security
software using or performing cryptographic functions with asymmetric
algorithms.  The form and manner of this Apache Software Foundation
distribution makes it eligible for export under the License Exception
ENC Technology Software Unrestricted (TSU) exception (see the BIS 
Export Administration Regulations, Section 740.13) for both object 
code and source code.

The following provides more details on the included cryptographic
software:
  Hadoop Core uses the SSL libraries from the Jetty project written 
by mortbay.org.

hdp2.5-hadoop's Issues

TestDelegationTokenRenewer#testRMRestartWithExpiredToken fails intermittently

Project: hadoop-yarn-server/hadoop-yarn-server-resourcemanager/

The test testRMRestartWithExpiredToken fails intermittently with the following error:

Stacktrace:
java.lang.AssertionError: null
at org.junit.Assert.fail(Assert.java:86)
at org.junit.Assert.assertTrue(Assert.java:41)
at org.junit.Assert.assertNotNull(Assert.java:621)
at org.junit.Assert.assertNotNull(Assert.java:631)
at org.apache.hadoop.yarn.server.resourcemanager.security.TestDelegationTokenRenewer.testRMRestartWithExpiredToken(TestDelegationTokenRenewer.java:1060)

RCA: The null value shown in the error is the value of the tokenBuffer which is obtained from the map. The ApplicationID and the value is populated in the map only when the new token is generated. The issue here seems like there is some delay in obtaining the HDFS token on some occasions which results in the null value.

TestKill.testKillJob fails: task remains in NEW state

In /HDP2.5-hadoop/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-app, below test case is failing sometimes.
TestKill.testKillJob:84 Task state not correct expected: but was:

RCA: When the task is in SCHEDULED state, when the event to kill the job is triggered, task is also being killed. But sometimes the task is remaining in the NEW state instead of going into the SCHEDULED state, when the event to kill the job is triggered.
