[jira] [Created] (HADOOP-11002) shell escapes are incompatible with previous releases

Allen Wittenauer created HADOOP-11002:
-----------------------------------------

             Summary: shell escapes are incompatible with previous releases
                 Key: HADOOP-11002
                 URL: https://issues.apache.org/jira/browse/HADOOP-11002
             Project: Hadoop Common
          Issue Type: Bug
          Components: scripts
            Reporter: Allen Wittenauer


Post-HADOOP-9902, the following in namenode opts doesn't work without being escaped:

{code}
-XX:HeapDumpPath=./java_pid_<pid>.hprof
{code}

This is a bit of surprising behavior to the users.  The breakage is directly result of the code that fixes spaces in directories.  Since it is much more likely to hit weird metacharacters in shell than have directories with spaces, that part of HADOOP-9902 needs to get replaced.
