> Some Hadoop shell scripts infer their own name using this bit of shell magic:
> {code}
>  18     MYNAME="${BASH_SOURCE-$0}"
>  19     HADOOP_SHELL_EXECNAME="${MYNAME##*/}"
> {code}
> e.g. see the [hdfs|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/bin/hdfs#L18] script.
> The inferred shell script name is later passed to _hadoop-functions.sh_ which uses it to construct the names of some environment variables. E.g. when invoking _hdfs datanode_, the options variable name is inferred as follows:
> {code}
> # HDFS + DATANODE + OPTS -> HDFS_DATANODE_OPTS
> {code}
> This works well if the calling script name is standard {{hdfs}} or {{yarn}}. If a distribution renames the script to something like foo.bar, , then the variable names will be inferred as {{FOO.BAR_DATANODE_OPTS}}. This is not a valid bash variable name.
