Cloudera cluster install hangs

[#1]

Hi,

When I login into Cloudera Manger it goes to the Cluster Installation wizard, where it says it is installing parcels, but just hangs and nothing happens.

I checked the log on the nodes and it gives those errors:

Anyone knows what this parcel.torrent file is suppose to do what, and how to resolve this python errors?

thank you,

I solved that parcel.torrent time-out problem. 

Found out the 4 agent nodes didn't have the hostname of the server in their host file. 

Now I just have to take care of those bits and pieces:

• There are mismatched versions across the system, which will cause failures. See below for details on which hosts are running what versions of components.
• Cloudera supports versions 1.6.0_31 and 1.7.0_55 of Oracle JVM and later. OpenJDK is not supported, and gcj is known to not work. Check the component version table below to identify hosts with unsupported versions of Java.
• Cloudera supports versions 1.6.0_31 and 1.7.0_55 of Oracle JVM and later. OpenJDK is not supported, and gcj is known to not work. Check the component version table below to identify hosts with unsupported versions of Java.
• Java version 6 not supported for CDH 5. You must use Java version 7.
• Cloudera recommends setting /proc/sys/vm/swappiness to a maximum of 10. Current setting is 60. Use the sysctl command to change this setting at run time and edit/etc/sysctl.conf for this setting to be saved after a reboot. You can continue with installation, but Cloudera Manager might report that your hosts are unhealthy because they are swapping.
