Hi,

I am instaling a new cluster with the latetest version of cloudera. 

In the /cmf/express-wizard/ I am adding my current machine as a client. 

The parcels get downloaded but never distributed.

in the logs I have something like : 

[07/Apr/2016 15:31:53 +0000] 2736 Thread-13 downloader INFO Current state: CDH-5.7.0-1.cdh5.7.0.p0.45-trusty.parcel [totalDownloaded=0 totalSize=1538531315 upload=0 state=downloading seed=['http://cron2:7180/cmf/parcel/download/CDH-5.7.0-1.cdh5.7.0.p0.45-trusty.parcel'] location=/opt/cloudera/parcels/.flood/CDH-5.7.0-1.cdh5.7.0.p0.45-trusty.parcel progress=0]
