Ambari HDP installation fails with no more mirrors to try error

[#1]

Hi all,

I'm trying to install hadoop components using ambari server and it is failing in the last step(install, start, test step). Everything looks fine to me, internet is working fine and yum repos also seems fine to me.

I tried to run the same command manually from terminal also and it worked perfectly. but the script is not able to run that command.

Can anyone please suggest what exactly the issue is. Attaching log and yum dir screenshots.

Are you using any proxy to access internet?

[#3]

not sure @Jitendra Yadav, I've to check with the system admin for proxy. Do we have to configure anything extra if we use a proxy ?

[#4]

can you please share the output of below command from that node where its failing?

yum list 'hadoop_2_4*-libhdfs*'

Here's the output for above command:

Hi @Jitendra Yadav, I just checked and yes it's behind a proxy.

[#7]

please follow this doc for ambari internet proxy setup.

I setup the proxy like this and still it's failing with same error message.

You added it in wrong way, you need to append those confs in AMBARI_JVM_ARGS variable. After that restart the ambari server.

export AMBARI_JVM_ARGS=$AMBARI_JVM_ARGS' -Xms512m -Xmx2048m -Djava.security.auth.login.config=/etc/ambari-server/conf/krb5JAASLogin.conf -Djava.security.krb5.conf=/etc/krb5.conf -Djavax.security.auth.useSubjectCredsOnly=false -Dhttp.proxyHost=proxy.sgp.hp.com -Dhttp.proxyPort=8080'

I modified the proxy setting and retried after restarting the ambari-server. This time it's throwing the following error:
