sorry I typed the wrong download url , its actually 2.5 repository so the url I used for downloading is https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.1.0/bk_ambari-installation/content/ambari_repositories.html I compared the checksum and it matches. below is the md5 file from the above site for this repository: ambari-2.5.1.0-centos6.tar.gz: 16 73 FB 17 7B 0A 59 3E 4B 6D 56 46 FD 68 94 E9 below is the md5 checksum of the tar ball after downloading from the above url. [root@hadoop1 ~]# md5sum ambari-2.5.1.0-centos6.tar.gz 1673fb177b0a593e4b6d5646fd6894e9 ambari-2.5.1.0-centos6.tar.gz can you or someone try to unzip it ?

hi Jay but as I have shown that the "no_proxy" variable is defined in my /etc/environment file but wget is not using it . I also tried adding the no_proxy variable to the wgetrc file but didn't help. [root@hadoop1 etc]# grep proxy /etc/wgetrc #https_proxy = http://proxy.yoyodyne.com:18023/ #http_proxy = http://proxy.yoyodyne.com:18023/ #ftp_proxy = http://proxy.yoyodyne.com:18023/ https_proxy = http://dotatofwproxy.tolls.dot.state.fl.us:8080/ http_proxy = http://dotatofwproxy.tolls.dot.state.fl.us:8080/ no_proxy=".tolls.do.state.fl.us,hadoop1.tolls.dot.state.fl.us,hadoop1" so how can I get wget to use the no_proxy variable? ...

hi Jay I found the issue I am facing but don't know why I am having issue this time and not the first time when I installed this cluster. here is the issue : wget should not be using proxy server to download the DBConnectionVerification.jar file because its local server , and for this I have defined "no_proxy" settings in the /etc/environment file as follows : [root@hadoop1 ~]# cat /etc/environment http_proxy="http://dotatofwproxy.tolls.dot.state.fl.us:8080/" https_proxy="https://dotatofwproxy.tolls.dot.state.fl.us:8080/" ftp_proxy="ftp://dotatofwproxy.tolls.dot.state.fl.us:8080/" no_proxy=".tolls.dot.state.fl.us,.to.dot.state.fl.us,10.0.0.0/8" so why does wgetrc not picking up the no_porxy settings ? ...
