Job Id's Colide due to lack of system entropy #25

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The random generator in crypto/rand produces strings of non random characters 
when it runs out entropy which will will eventually produce a job id collision. 

Example:
scheme: https host: glados.systemsbiology.net port: 8083
{
   "FirstCreated": "Tue Aug 23 17:10:41 PDT 2011",
   "JobId": "1a9058d2000000000000000000000000",
   "Label": "1a9058d2000000000000000000000000",
   "LastModified": "",
   "Owner": "Anonymous",
   "Progress": {
       "Errored": 0,
       "Finished": 0,
       "Total": 100
   },
   "Running": false,
   "Scheduled": false,
   "Type": "Unspecified",
   "Uri": "/jobs/1a9058d2000000000000000000000000"
}

It is not clear if this is an issue with the server configuration or golang.

This is a system configuration error. It was being caused by low entropy 
production on the servers and hadoop's use of buffered io to load random 
numbers draining the entropy pool.
