Bjorn Olsen created AMBARI-25174:
------------------------------------
Summary: OneFS Mpack missing configuration settings needed for
Spark2
Key: AMBARI-25174
URL: https://issues.apache.org/jira/browse/AMBARI-25174
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.7.3
Environment: HDP 3.1.1 using OneFS instead of HDFS
Isilon 8.2.1.0 (simulator)
isilon-onefs-mpack-1.0.0.0
Reporter: Bjorn Olsen
The OneFS management pack does not include the below HDFS
configurations/parameters. If using the OneFS mpack as a replacement for the
HDFS service, these parameters no longer exist.
{{dfs.datanode.kerberos.principal=hdfs/_HOST@<MY REALM>
dfs.datanode.keytab.file=/etc/security/keytabs/hdfs.service.keytab
dfs.namenode.kerberos.principal=hdfs/_HOST@<MY REALM>
dfs.namenode.keytab.file=/etc/security/keytabs/hdfs.service.keytab }}
These are required by Spark2 in a Kerberised environment, and Spark2 will fail
with obscure errors "Failed on local exception: java.io.IOException: Couldn't
set up IO streams: java.lang.IllegalArgumentException:
Failed to specify server's Kerberos principal name"
when these parameters do not exist.
