Long Zhou updated HTRACE-25:
----------------------------
Attachment: HTRACE-25.002.patch
rewrite the patch following [~cmccabe]'s suggestion.
- TraceSink.java implements a Flume sink that can forward received spans to
SpanReceiver. It uses htrace-core public APIs, and can be configured to work
with any SpanReceiver implementation.
- MilliSpan.java: added parseJson function so that core APIs do not leak
Jackson library. Without this function, htrace-flume (or other callers) will
load its own copy of Jackson to deserialize MilliSpan, and it conflicts with
the shaded Jackson library in htrace-core.
- Span.java: define Json field names, so that they can be reused in
FlumeSpanReceiver.java
- TestMilliSpan.java: refactor compareSpans function, so that it can be reused
in TestTraceSink.java
- FlumeSpanReceiver.java: use short field names for event headers
- TestFlumeSpanReceiver.java: move common functions to
FlumeSpanReceiverTestUtility.java so that they can be reused
- TestTraceSink.java: added end-to-end test cases for FlumeSpanReceiver and
TraceSink
- README.md: added TraceSink setup instructions, fixed formatting.
