Vikas, This message is normal and harmless.
2013-04-29 08:26:11,868 (conf-file-poller-0) [DEBUG - org.apache.flume.conf.file.AbstractFileConfigurationProvi der$FileWatcherRunnable.run(AbstractFileConfigurationProvider.java:188)] Checking file:conf/flume.conf for changes If you change your log settings to INFO level it will also not show up. Regarding the reason for which you do not see the contents of your file in hdfs. One thing with the exec source and tail is that the events are buffered until 20 events have been written to the cache. One way to work around this is to change the default from 20 -> 1 batchSize 20 The max number of lines to read and send to the channel at a time Alternatively there was a recent patch that sets the batchTimeout for exec source that will let you flush the cache based on elapsed time. That fix is available on the latest version of trunk. -Jeff On Mon, Apr 29, 2013 at 8:31 AM, Vikas Kanth <[email protected]>wrote: > Hi, > > I am getting following message in loop.
