Yeah, thats right. Unfortunately there is no feature available to gather Nifi Lineage in Navigator.

@venkatsambath I think and the same, we have analized its parents directories and apparently they are fine. # ls -ln /var/lib/ambari-agent/tmp/hadoop_java_io_tmpdir/libleveldbjni-64-1-6110205147654050510.8 ls: cannot access /var/lib/ambari-agent/tmp/hadoop_java_io_tmpdir/libleveldbjni-64-1-6110205147654050510.8: No such file or directory # id yarn uid=1075(yarn) gid=1051(hadoop) groups=1051(hadoop) I have managed to start the node from the command line, but I have detected that the command that is executed from Ambari, sets the permissions of the path "hadoop_java_io_tmpdir" as owner to the user "hdfs:hadoop", however I do not identify why the user yarn does not have permissions writing and execution, the permissions are 1777 and the yarn user is member of hadoop group.

This is much clear now On server side the request was rejected as the client was initiating non-ssl connection Caused by: org.apache.thrift.transport.TTransportException: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection? Client side it was unable to trust the server certs as it was not configured to use a truststore Caused by: com.cloudera.hiveserver2.support.exceptions.GeneralException: [Cloudera][HiveJDBCDriver](500164) Error initialized or created transport for authentication: [Cloudera][HiveJDBCDriver](500169) Unable to connect to server: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target. You got to add few more properties to your connection string jdbc:hive2://vdbdgw01dsy.dsone.3ds.com:10000/default;AuthMech=1;KrbAuthType=1;KrbHostFQDN=vdbdgw01dsy.dsone.3ds.com;KrbRealm=DSONE.3DS.COM;KrbServiceName=hive;LogLevel=6;LogPath=d:/TestPLPFolder/hivejdbclog;SSL=1;SSLTrustStore=<path_to_truststore>;SSLTrustStorePwd=<password to truststore> If you dont have password to your truststore you can omit the parameter SSLTrustStorePwd

The SSH connection is established initially at the beginning of the action and the <command> tag executes the command passed within the tags, but it takes a while(~ around 3 hours) for the command to execute, and in the meantime this action gets updated to COMPLETED and proceeds on to the next subsequent action, whereas former command is still in execution phase. This exception arises when Oozie starts on the latter SSH action while the prior SSH action is still in execution. So why does Oozie presumes the prior SSH action as completed yet the command is still in process?

Have you considered creating a copy of the table as external (in new location you want) and then INSERT into NewTable SELECT * FROM OldTable?

Thanks Venkat!

That command worked a treat, I wasn't aware that the configuration xmls varied based on the purpose of the host they are deployed to. I've got the superuser running now, thanks for the help

Thanks @venkatsambath. It worked.

Assuming you used the same certs, or even if you user different ones; you should be able to click the lock in any SSL based UIs (Ambari, Ranger, Nifi, yarn, grafana, etc) in your browser. This will show you all details of the certs including expiration dates.
