N/A	BUG-94823	Upgrading Ambari 2.5.x to 2.6.x and AMS to 2.6.1 without changing the JDK version from 1.7 to 1.8 causes the Metrics Collector services start to fail. The Ambari Metrics Collector 2.6.1 requires JDK 8. Traceback (most recent call last): File "/var/lib/ambari-agent/cache/common-services/AMBARI_METRICS/0.1.0/package/scripts/service_check.py", line 207, in <module> AMSServiceCheck().execute() File "/usr/lib/python2.6/site-packages/resource_management/libraries/script/script.py", line 375, in execute method(env) File "/usr/lib/python2.6/site-packages/ambari_commons/os_family_impl.py", line 89, in thunk return fn(args, *kwargs) File "/var/lib/ambari-agent/cache/common-services/AMBARI_METRICS/0.1.0/package/scripts/service_check.py", line 159, in service_check raise Fail("All metrics collectors are unavailable.") resource_management.core.exceptions.Fail: All metrics collectors are unavailable.	Upgrade the JDK version only for the AMS Metrics Collector. Only on the metrics collector host, do the following: wget -O /tmp/jdk-8u112-linux-x64.tar.gz http://public-repo-1.hortonworks.com/ARTIFACTS/jdk-8u112-linux-x64.tar.gz cd /usr/jdk64 tar -xzf /tmp/jdk-8u112-linux-x64.tar.gz wget -O /tmp/jce_policy-8.zip http://public-repo-1.hortonworks.com/ARTIFACTS/jce_policy-8.zip cd /usr/jdk64/jdk1.8.0_112/jre/lib/security unzip -o /tmp/jce_policy-8.zip cp UnlimitedJCEPolicyJDK8/local_policy.jar UnlimitedJCEPolicyJDK8/US_export_policy.jar . rm -r UnlimitedJCEPolicyJDK8 rm /tmp/jdk-8u112-linux-x64.tar.gz /tmp/jce_policy-8.zip In Ambari Web, go to Services > Ambari Metrics > Advanced ams-hbase-env > ams-env template. Change export JAVA_HOME={{java64_home}} to export JAVA_HOME=/usr/jdk64/jdk1.8.0_112 Restart the Metrics Collector service.
N/A	BUG-82900	If hosts are in maintenance mode during the Enable Kerberos wizard, the kerberos client is not installed, and keytabs and principals are not created for these hosts.	Take the host out of Maintenance Mode. Use Install Clients on Host detail page of the host to install all of the clients which will include the Kerberos client. Regenerate keytabs using Admin > Kerberos > Regenerate Keytabs.
N/A	Bug-93305	Oozie Spark workflows are failing with the following exception due to missing py4j and pyspark files after patch upgrade: Failing Oozie Launcher, Main class [org.apache.oozie.action.hadoop.SparkMain], main() threw exception, Missing py4j and/or pyspark zip files. Please add them to the lib folder or to the Spark sharelib. org.apache.oozie.action.hadoop.OozieActionConfiguratorException: Missing py4j and/or pyspark zip files. Please add them to the lib folder or to the Spark sharelib.	The workaround is to manually copy these files to HDFS. To do that follow the steps below: On the Oozie server, using the HDFS client, find the new sharelib location for the patched Oozie: # su - oozie $ hdfs dfs -ls /user/oozie/share/lib Found 2 items drwxr-xr-x - oozie hdfs 0 2017-12-14 16:45 /user/oozie/share/lib/lib_20171214164505 drwxr-xr-x - oozie hdfs 0 2017-12-18 18:56 /user/oozie/share/lib/lib_20171218185543 As the Oozie user, upload Spark files to the new location. $ cd /usr/hdp/2.6.3.0-86/spark/lib $ hdfs dfs -put datanucleus-* /user/oozie/share/lib/lib_20171218185543/spark $ cd ../python/lib/ $ hdfs dfs -put py*.zip /user/oozie/share/lib/lib_20171218185543/spark
