Is there a way by which we can find the dependent packages of hadoop and OS/Environments?

[#1]

Is there a command or tool by which we can check the list of dependent libraries or files between hadoop and OS(environment)?

For eg: When we install ambari on RHEL, we have to manually install "libtirpc-devel". Thusa, is there a way by which we can check the hadoop packages that are dependent on "libtirpc-devel".

We can query the depepdencies using "repoquery" which is available as part of package "yum-utils" Example:

# yum install yum-utils -y
          And then you can try something like this. 
# for i in `rpm -qa | grep hadoop` ; do echo "Package [$i]:"; rpm -q --requires $i ; echo ; done

Example: For ambari dependencies on CentOS6

for i in `rpm -qa | grep ambari-server` ; do echo "Package [$i]:"; rpm -q --requires $i ; echo ; done
Package [ambari-server-2.5.0.3-7.x86_64]:
postgresql-server >= 8.1
openssl  
python >= 2.6
/bin/sh  
/bin/sh  
/bin/sh  
/bin/sh  
rpmlib(PartialHardlinkSets) <= 4.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadIsXz) <= 5.2-1

Thanks for it. And is there any other way round as well? Like for an particular rpmlib, can we find the list of HDP packages as well?

You might also want to try the following using "--tree-requiers" to see dependency tree.

# repoquery --tree-requires --recursive --resolve ambari-server
