I am using GNU coreutils 8.4 with flume 1.4.0, log4j 1.2.17. I've found a problem that sometimes tail run by flume is reading a file has been renamed by log4j.
flume executed tail with following parameters: tail -F logfilename Fist flume had run the command, I checked file descriptors opened by tail process: ls -l /proc/pid/fd 0 -> pipe:[185694192] // Sorry, I am not sure that the numbers are correct. 1 -> pipe:[185694193] 2 -> pipe:[185694194] 4 -> inotify 5 -> logfilename After time passed, log4j had rotated the log file, I rechecked file descriptos: ls -l /proc/pid/fd 0 -> pipe:[185694192] // Sorry, I am not sure that the numbers are correct. 1 -> pipe:[185694193] 2 -> pipe:[185694194] 4 -> inotify 5 -> logfilename.1 tail has been being executed with a parameter '-F', but didn't follow by name. This problem doesn't happen always. I don't know why this problem happened.
