Hi Guys,

I''m unable to start DataNode in ambari 2.1.2. I tried all the suggested solutions in the community and Internet and without any success to solve it.

Here the important error files from

var/lib/ambari-agent/data/

Run the below command to check if JCE is Unlimited.To avoid several Kerberos issues, Java Cryptography Extension (JCE) should be unlimited. If JCE is unlimited, then 'local_policy.jar' should contain keyword 'CryptoAllPermission'

$ zipgrep CryptoAllPermission $JAVA_HOME/jre/lib/security/local_policy.jar

In my case the ouput is as below which is expected default_local.policy: permission javax.crypto.CryptoAllPermission

$ zipgrep CryptoAllPermission /usr/jdk64/jdk1.8.0_112/jre/lib/security/local_policy.jar 
default_local.policy: permission javax.crypto.CryptoAllPermission;

How to Install JCE

Go to the Oracle Java SE download page http://www.oracle.com/technetwork/java/javase/downloads/index.html
Scroll down ... Under "Additional Resources" section you will find "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy File"
Download the version that matches your installed JVM E.g. UnlimitedJCEPolicyJDK7.zip
Unzip the downloaded zip
Copy local_policy.jar and US_export_policy.jar to the $JAVA_HOME/jre/lib/security (Note: these jars will be already there so you have to overwrite them)
Then restart your application to get rid of this exception.

Then try to restart the datanode.

@Florin Miron

Yeah that's quite disappointing the files you have attached are not exhaustive, can you upload the below files.

/var/log/hadoop/hdfs/hadoop-hdfs-datanode-node.bigdata.com.log 
/var/log/ambari-server/ambari-server.log

This could help in the diagnostics

This error might arise if you do not start namenode as hdfs user. Actually, you are trying to run it as root user but the file /hadoop/hdfs/namenode/in_use.lock is owned by hdfs user. Do not use sudo to start hadoop processess. Try to start it without sudo. Try this:

su -l hdfs -c "/usr/hdp/current/hadoop-hdfs-namenode/../hadoop/sbin/hadoop-daemon.sh start namenode"

Can you try that and revert
