[0.90RC1] bin/hbase script displays "no such file" warning on target/cached_classpath.txt
-----------------------------------------------------------------------------------------

                 Key: HBASE-3383
                 URL: https://issues.apache.org/jira/browse/HBASE-3383
             Project: HBase
          Issue Type: Bug
          Components: shell
    Affects Versions: 0.90.0
         Environment: Ubuntu 10.10 Server
            Reporter: Tatsuya Kawano
            Priority: Trivial
             Fix For: 0.90.0


HBase version: 0.90 release-candidate-1

bin/hbase blindly creates "target" directory and fails to generate "target/cached_classpath.txt"
if it's in the binary (pre-built) distribution. 

{code}
$ bin/hbase shell
cat: ... /hbase-0.90.0/bin/../target/cached_classpath.txt: No such file or directory
HBase Shell; enter 'help<RETURN>' for list of supported commands.
{code}

{code:title=bin/hbase}

112: add_maven_deps_to_classpath() {
113:   # The maven build dir is called 'target'
114:   target="${HBASE_HOME}/target"
115:   if [ ! -d "${HBASE_HOME}/target" ]
116:   then
117:     mkdir "${target}"
118:   fi
119:   # Need to generate classpath from maven pom. This is costly so generate it
120:   # and cache it. Save the file into our target dir so a mvn clean will get
121:   # clean it up and force us create a new one.
122:   f="${target}/cached_classpath.txt"
123:   if [ ! -f "${f}" ]
124:   then
125:     ${MVN} -f "${HBASE_HOME}/pom.xml" dependency:build-classpath -Dmdep.outputFile="${f}"
&> /dev/null
126:   fi
127:   CLASSPATH=${CLASSPATH}:`cat "${f}"`
{code}

Maybe we can simply skip this process if "target" directory doesn't exist.
