Logstash-forwarder is failing to install on CentOS Linux release 7.3.1611

[Nagesh74]

[exec] Step 9 : RUN mkdir /opt/logstash/ssl;mkdir -p /opt/dw-logstash/initScripts; mkdir -p /opt/cleanup/ && yum -y update && yum clean all

 [exec]  ---> Running in 7f0a594dba42

 [exec] [91m/bin/sh: 1: yum: not found

 [exec] The command '/bin/sh -c mkdir /opt/logstash/ssl;mkdir -p /opt/dw-logstash/initScripts; mkdir -p /opt/cleanup/ &&     yum -y update &&     yum clean all' returned a non-zero code: 127

Earlier it used to run below command I see the previous build from 9/22 shows just: [exec] Step 9 : RUN mkdir /opt/logstash/ssl;mkdir -p /opt/dw-logstash/initScripts; mkdir -p /opt/cleanup/     but the latest build today shows RUN mkdir /opt/logstash/ssl;mkdir -p /opt/dw-logstash/initScripts; mkdir -p /opt/cleanup/ && yum -y update && yum clean all

I am closing this issue as I found it is invalid.
