AdaptorId should be persistent even after an agent restart
----------------------------------------------------------
Key: HADOOP-5354
URL: https://issues.apache.org/jira/browse/HADOOP-5354
Project: Hadoop Core
Issue Type: Bug
Components: contrib/chukwa
Reporter: Jerome Boulon
In case of agent restart, an adaptor may not get the same adaptorId.
1)The adaptorId is sent back to the remote application after the Add command.
Now, let suppose the agent dies and restarts.
Each new adaptor created from the checkpoint will now have another adaptorId
.
If the remote application tries to stop/shutdown only using the adaptorId
received in step (1), the command may be sent to the wrong adaptor.
if the adaptorId in for example an MD5 of the command line we don't need to
save any additional information inside the checkpoint.
This will change the current API from int to String.
