Hello. Seems like an issue around Cloudera (not sure). I faced with something like that when cluster was deployed without Oozie. Could please try to deploy cluster with Oozie server?

Hi all,

I installed sahara on Openstack liberty version, and I succeed to deploy CDH-5.4 without any error. But When I login to the Cloudera-manager VM, I found some wrong Hadoop/HDFS configurations:

[root at int32bit-hadoop-1-cdh-master-001 hdfs]# hdfs dfs -df
Filesystem         Size        Used    Available  Use%
file:///    20061442048  5187198976  14874243072   26%

I checked the hadoop config file in /etc/hadoop/conf, it seemed that the Cloudera-manager fail to update config:

[root at int32bit-hadoop-1-cdh-master-001 hdfs]# cat /etc/hadoop/conf/core-site.xml
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?> 


As showed above, the core-site.xml is empty.

Then I checked other config files, it showed the same result with empty configuration.

Here's my master role processes:


and slave role processes:



verbose = true
log_dir = /var/log/sahara
use_syslog = false
use_stderr = true
rpc_backend = rabbit
use_floating_ips= True
use_neutron = true
use_namespaces = true
use_rootwrap = true
rootwrap_command="sudo sahara-rootwrap /etc/sahara/rootwrap.conf"

plugins = vanilla,hdp,spark,cdh,ambari,fake,mapr,storm
infrastructure_engine = heat


Any help is greatly appreciated.
