Hi all, I originally deployed a 6 node cluster using Cloudera Manager and specified root + root's ssh key. I would like to now move this to use a non-privileged account that has passwordless sudo, but I don't see how to do this. Is this possible? David

Setting parcel_dir=/data/cloudera/parcels in /etc/cloudera-scm-agent/config.ini fixed the prob (service cloudera-scm-agent required). Currently it will not follow a symlink from /opt/cloudera -< /data/cloudera properly. Before updating config.ini I couldn't deploy any additional parcels besides CDH and these were popping up in /var/log/cloudera-scm-agent/clouder-scm-agent.log [16/Sep/2013 18:43:21 +0000] 47072 Thread-13 parcel_cache INFO Unpacking /opt/cloudera/parcel-cache/HADOOP_LZO-0.4.15-1.gplextras.p0.24-el6.parcel into /opt/cloudera/parcels [16/Sep/2013 18:43:21 +0000] 47072 MainThread parcel INFO Loading parcel manifest for: CDH-4.4.0-1.cdh4.4.0.p0.39 [16/Sep/2013 18:43:21 +0000] 47072 MainThread parcel INFO Loading parcel manifest for: HADOOP_LZO-0.4.15-1.gplextras.p0.24 [16/Sep/2013 18:43:21 +0000] 47072 MainThread parcel INFO Loading parcel manifest for: CDH [16/Sep/2013 18:43:21 +0000] 47072 MainThread parcel ERROR Exception while reading parcel: CDH Traceback (most recent call last): File "/usr/lib64/cmf/agent/src/cmf/parcel.py", line 103, in refresh pid = ParcelId.dir(child) File "/usr/lib64/cmf/agent/src/cmf/parcel_id.py", line 74, in dir raise Exception("Invalid parcel directory: %s" % (dir)) Exception: Invalid parcel directory: CDH [16/Sep/2013 18:43:21 +0000] 47072 MainThread parcel ERROR Exception while refreshing parcel repository.

I'm using CDH 4.4.0-1.cdh4.4.0.p0.39 on CentOS 6 and am having trouble with changing the parcel path from /opt/cloudera to /data/cloudera (I know I can symlink it, but the field is there in CM, so why not try to do it the right way right?).
I went ahead and changed the parcel path via the CM UI to /data/cloudera/parcel-repo. Then I added a new host to the cluster, but to my surprise, I see the /opt/cloudera tree has been created and populated with parcels on the new host and nothing is in /data.
Am I missing an option to completely move the parcel path?
