    • Type: Bug

    • Priority: Minor
    • Resolution: Fixed
    • Affects Version/s: None

    • Release Note:
      Updates hadoop-config.sh to always resolve symlinks when determining HADOOP_HOME. Bash built-ins or POSIX:2001 compliant cmds are now required.

      Description

      The link resolution logic in bin/hadoop-config.sh fails when when executed via a symlink, from the root directory. We can replace this logic with cd -P and pwd -P, which should be portable across Linux, Solaris, BSD, and OSX.
