Could you check if you have multiple Java being installed in your node,
this could also be the issue .
/usr/lib/jvm or -alternatives --config java
if you have OpenJdk then it could also be the issue.
Just remove all Openjdks and have one java with 1.7 or higher.
Thanks for the reply!! , will check this.
BTW , after uninstalling cloudera manager , now i am facing this new issue :
http://archive.cloudera.com/cm5/redhat/7/x86_64/cm/5/RPMS/x86_64/cloudera-manager-daemons-5.11.0-1.c...: [Errno -1] Package does not match intended download. Suggestion: run yum --enablerepo=cloudera-manager clean metadata
Trying other mirror.
Error downloading packages:
cloudera-manager-daemons-5.11.0-1.cm5110.p0.101.el7.x86_64: [Errno 256] No more mirrors to try.
Tried multiple times on different hosts, seeing this errror on all the hosts since past 2 days. Can you please let me know what can be done in this case.
Manually i am able to download this rpm.
I had the same issue last week , it was due poor internert connectivity or issue with cloudera mirrors.
it will find another alternative mirros if it couldnt find one .
so you mean to say that you had uninstalled everything and going for fresh install ?
I am 100% confident that it is due to multiple java being installed in that particular node , you could have find it yum also by doing a search.
Thanks for the quick response.
Yes, i am going for fresh install.
I was just able to install cdh manager on a test node successfully. Now trying it on my actual manager host.
I see , my hosts only has 1 Java version installed.

There is 1 program that provides 'java'.
*+ 1 java-1.8.0-openjdk.x86_64 (/usr/lib/jvm/java-1.8.0-openjdk-188.8.131.52-0.b13.el7_3.x86_64/jre/bin/java)
Sounds good . :)
Make sure all your repos are disabled except Cloudera , because when you reboot your systems its going to update its yum if some other applications needs java then its gonna push all the openjdks and you might fall in trouble .
I usually make it disable and enable repo when I want . Just quick tip mate . to have hassel free hadoop admin JOb :))
I tried fresh install again, but again its stuck at same point. As suggested, i dont see multiple java versions installed.
I am able to telnte the cloudera manager agent port (9000) from the Cloudera manager hosts to other cluster hosts running agent.
When checked manually i see same version across all hosts.
