I have a hadoop environment with tarball which I downloaded at http://hadoop.apache.org/releases.html#Download.
Then, I must use cloudera manager to monitor my mapreduce application.
is possible using cloudera manager without cdh installation?
Cloudera Manager is useless without CDH. Any reason why you would not just use that? Usually the question is the other way around ("I have CDH installed, do I need to use Cloudera Manager?")
