> Need to fix the eval expression. We can relace single quote with escape-char
> and a double quote.
>
> HADOOP_OPTS can contain -XX:OnOutOfMemoryError='kill -9 %p', this leads to
> following invalid eval expression - eval $HADOOP_OPTS='foo_bar
> -XX:OnOutOfMemoryError='kill -9 %p''
> Replacing with escape-char and a double quote should works fine.
>
> eval "$1"="'${!1} $3'" -> eval "$1"="\"${!1} $3\""
> eval "$1"="'${!1# }'" -> eval "$1"="\"${!1# }\""
