Zeppelin 0.8.0 dose not recognize "-" character when the interpreter when
interpreter contains "-" character：
if I display then specified interpreter name and the interpreter contains "-"
character，it will report the following error:
{color:#FF0000}org.apache.zeppelin.interpreter.InterpreterNotFoundException:
Either no interpreter named mobin or it is not binded to this note{color}
on the cintrary, if I don't refer to the interpreter,it works
Then, I debugged the source code and found that the bug was caused by a line of
regular expression code of class Paragraph
private static Pattern REPL_PATTERN = Pattern.compile("(\\s*)%([\\w\\.]+).*",
Pattern.DOTALL)
[https://github.com/apache/zeppelin/blob/v0.8.0/zeppelin-zengine/src/main/java/org/apache/zeppelin/notebook/Paragraph.java]]
So I extracted this regular expression code to test and changed the regular
expression ,as shown in the figure.
