Unable to Locate Hadoop core-site.xml and hdfs-site.xml files in HDP

[#1]

I have to copy the core-site.xml and hdfs-site.xml from HDP but I am unable to locate this folder. As per the documentation, these files are placed at /etc/hadoop/ but when I go to etc folder I can not find any folder named "Hadoop".

On this host where the HDP components are installed it can be found in the same directory as following:

So may be you are looking on an incorrect host. Please check if any HDP component is running on that host or not like following , (this is just to verify the hdp installation):

# ps -ef | grep DataNode
# ps -ef | grep NameNode
# hdp-select

.

If you want to download the "core-site.xml" and "hdfs-site.xml" for client side usage then it is an easiest option to download the client config from ambari UI.

Ambari UI --> "HDFS" --> "Service Action" --> "Download Client Configs"

### That will give you the following downloaded files:

core-site.xml        hadoop-env.sh        hdfs-site.xml        log4j.properties

.

It looks like you are not looking on the correct host. Can you confirm if logged onto to the correct host.
