Arpit Agarwal commented on HDFS-7591:
-------------------------------------

Hi Chris,

Should the following check be {{if [[ "$#" -gt 0 ]]}}?

i.e we echo $CLASSPATH if the number of arguments is zero, else we launch _Classpath_. I think
I missed the same issue when code reviewing HADOOP-10903 (my apologies!) for _hadoop classpath_.

{code}
+    if [[ "$#" -eq 1 ]]; then
+      CLASS=org.apache.hadoop.util.Classpath
+    else
+      hadoop_finalize
+      echo "${CLASSPATH}"
+      exit 0
{code}

> HADOOP-10903 enhanced the {{hadoop classpath}} command to support optional expansion
of the wildcards and bundling the classpath into a jar file containing a manifest with the
Class-Path attribute.  The other classpath commands should do the same for consistency.
