I use TAILDIR sink in flume 1.7 to catch file changed in some folders and sink to HDFS, but after start flume,
some source runs well, some source causes Channel-closed error. ERROR [PollableSourceRunner-TaildirSource-source-error] (org.apache.flume.source.taildir.TaildirSource.process:236) -Unable to tail files java.lang.IllegalStateException: Channel closed [channel-cccc]. Due to java.io.EOFException: null .. Caused by : java.io.EOFException .. Sometimes, souce folder has not been generated files, Does this the reason? How to avoid this problem? Thanks.
