I want to use chuwka to collect the log generated by java log4j.

The log file has the size limition ,when the size reaches to 200M , the
log4j will rename this file to .1 and renew a log file.

If chukwa is tailing the current log , and the log size reaches to 200M but
the chukwa just collect < 200M . And the the log is renamed , a new log
file is generated.

I thought this log will miss , the chukwa will read the new log .But i
found the chukwa adaptor file offset doesn't change to 0 .

How chukwa handle this situation?

thx
