Description

In mesos_containerizer.cpp the containerized always sets HADOOP_HOME to what's passed to the slave as --hadoop_home.

Therefore even if --hadoop_home is unset, the check in hdfs.hpp is always true and getting the hadoop binary from $HADOOP_HOME or $PATH passed to the mesos-slave doesn't work. It tries to load hadoop from /bin/hadoop in this case.

This is a new regression in 0.18.
