Hi Divyani, it seems that you have set the IP "10.*.*.44" for the Cloudera Manager server (cloudera-scm-server). Can you set the correct IP or hostname for the "server_host" parameter in the /etc/cloudera-scm-agent/config.ini file?

[#3]

I am getting the same kind of error. and not able to get the config.ini file i the /etc/cloudera-scm-server folder.

@Divyani @Sats 

did you install the cloudera-manager-server and cloudera-manager-agent rpm ? 

the default config file path would be 

/etc/cloudera-scm-agent/config.ini

change the server_host 

[#5]

@Sats

if you want to change any thing in the cloudera manager config 

checkout  the below path 

/etc/default/cloudera-scm-server

[#6]

Hi @csguna - 

Below is what i could see in the 

/etc/default/cloudera-scm-server

Not sure where to make the server host change. Kindly let me know your inputs.

#
# Specify any command line arguments for the Cloudera SCM Server here.
#

CMF_SERVER_ARGS=""

#
# Locate the JDBC driver jar file.
#
# The default value is the default system mysql driver on RHEL/CentOS/Ubuntu
# and the standard, documented location for where to put the oracle jar in CM
# deployments.
#

export CMF_JDBC_DRIVER_JAR="/usr/share/java/mysql-connector-java.jar:/usr/share/java/oracle-connector-java.jar"

#
# Java Options.
#
# Default value sets Java maximum heap size to 2GB, and Java maximum permanent
# generation size to 256MB.
#

export CMF_JAVA_OPTS="-Xmx2G -XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp"

@Sats

Could you check the below path , thats were you can change the server_host -

/etc/cloudera-scm-agent/config.ini

, if you did not find one that means you havent installed cloudera scm agent

Hi All,

Thank you for your resolution. I was able to resolve the issue. The issue was with /etc/hosts file and the firewall service was also running, so stopped that as well.
