samza-core/src/main/scala/org/apache/samza/storage/TaskStorageManager.scala (line 173) <https://reviews.apache.org/r/52476/#comment236527> Looks like this log statement belongs in an else-block. It says the store is stale, but in this block, we've determined hasValidOffsetFile=true. Also the wording isn't entirely accurate. The offset file may be present, but empty. It might be better to say "Offset file is not valid for store: %s" - Jake Maes On Feb. 8, 2017, 8 p.m., Shanthoosh Venkataraman wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
