The reason for logging the exception is that it helps troubleshooting what caused the {{IOException}}, as it can come from two different calls from the try-catch. I came across a case where {{ tgt.getEndTime() }} was returned null and it resulted in an {{NPE}}. I see that you handled this with HADOOP-15593, but apart from logging the fact that the ticket's endDate was null, we have not logged the exception at all. Hope this is clear. was (Author: snemeth): Hi [~gabor.bota]!
