I am new in this subject. I have been following directives in Hadoop for Dummies book. At step 2 while trying to install bigtop, got this error in below.
OS : windows 8 VM: Centos6
just solved it, it was because of the expired link , it was replaced with https://archive.apache.org/dist/bigtop/bigtop-0.7.0/repos/centos6/bigtop.repo
