------------------------------------
Labels: easyfix patch (was: )
> NullPointerException not handled in JSONHandler
> -----------------------------------------------
>
> Key: FLUME-2719
> URL: https://issues.apache.org/jira/browse/FLUME-2719
> Project: Flume
> Issue Type: Bug
> Components: Sinks+Sources
> Affects Versions: v1.5.1
> Reporter: Gonzalo Herreros
> Priority: Minor
> Labels: easyfix, patch
> Attachments: FLUME-2719.patch
>
>
> When using an http source with JSONHandler, invalid json is handled correctly
> and a 400 error is returned.
> However an empty body provokes and unhandled NPE in JSONHandler which returns
> a 500.
> If should either ignore the request or complain the request is invalid.
> try {
> eventList = gson.fromJson(reader, listType);
> } catch (JsonSyntaxException ex) {
> throw new HTTPBadRequestException("Request has invalid JSON Syntax.",
> ex);
> }
> for (Event e : eventList) {
> ((JSONEvent) e).setCharset(charset);
> }
> The GSON API describes that fromJson returns null when the imput is EOF
> (which is arguable but documented).
> Flume should check for eventList being null before trying to loop
> Always reproduced in all version
