Timeline service depends on hbase.
By default, Timeline start a embedded hbase server by exuecting
\{stack_root}/\{version}/usr/lib/hbase/bin/hbase-daemon.sh.
So if hbase is not installed, hbase-daemon.sh file does not exist, So Timeline
service will fail to start.
// YARN params_linux.py
yarn_atsv2_hbase_versioned_home =
format("\{stack_root}/\{version}/usr/lib/hbase")
yarn_hbase_bin = format("\{yarn_atsv2_hbase_versioned_home}/bin")
// YARN hbase_service.py
daemon_script = format("\{yarn_hbase_bin}/hbase-daemon.sh")
