Cloudera Manager Hangs When Installing Parcels

New Contributor

Hello,

Been working with Cloudera for about 2 years now and up until recently, when the Cloudera Express 5.9 version was released, I had no issue adding a cluster. Starting with 5.9, when adding a cluster, I can find and select the hosts, parcels, install the CM agent and get a good status on a heartbeat. When the Installing Selected Parcels step comes in, I show 100% downloaded, but 0/0 in Distributed, Unpacked, and Activated. The issue exists regardless of which parcel or how many types I choose to install. My logs show the new cluster has no member hosts. I then have to open a new window, add the hosts to the cluster, distribute and upgrade CDH to get the parcels to distribute, unpack, and activate.

 

I thought it may have been a bug within the Cloudera Express 5.9.1, so I stood a new server up and installed the trial version of Enterprise Data Hub 5.10.1 only to have the same result. I can't find Cloudera reporting this as a known issue or any other instances of this exact problem. Can someone please help?

 

My configuration is an AWS environment with a single RHEL 6.8 (CE 5.9.1) and RHEL 7.3 (EDH 5.10.1) server; I am not running single-user mode.

 

Below is from the Enterprise Data Hub trial version 5.10.1, however the same errors and issues exist in the Express 5.9.1 version.

 

 

An excerpt of the log:

The hosts have the agent installed and appear in good condition:

Thanks in advance.
