---------------------------------
What is the status of this ticket? Any plan to get it released into next
release?
We had a similar issue on version 1.8.0 with kafka source, file channel and
hdfs sink (S3). Rather than having both .tmp and the actual log file, we had an
empty log file (.tmp was likely being deleted). The error happened like once or
twice everyday. So we have lost data when it happened.
