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

tsk — Thu, 01 Jun 2017 21:28:37 GMT

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

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

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

@Jay SenSharma

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?
