Starting adaptors in starting chukwa

after reading the chukwa starting log ,  the chukwa will  first read
the chukwa_agent_checkpoint file and the read the initial_adaptors file.

The chukwa_agent_checkpoint recorded the position of log transferring  ,
and the adaptors of chukwa when chukwa stopped .

When i restart chukwa , the chukwa will read both files. Will the adaptor
in initial_adaptors cover the adaptor in chukwa_agent_checkpoint ? These
adaptors has the same name and the file , just different offset .

The Adaptor is validated with adaptor name, data type, and parameters.  It doesn't validate offset.

Adaptors in initial_adaptors would not start, if the same adaptors
already exist in checkpoint file.
