Thanks Li Lu (inactive) for the patch,
Small nits :
- we can check for LOG.isDebugEnabled() before logging the debug message.
- Debug message can contain eventType which would be helpfull in analyzing else "Timeline entities are successfully put" will be of not much help.
- May be this logging information can be extracted to a method as checkstyle is hinting at larger method size ?
IMO as its logging test case is not required.
