[user@cdh03 CDH-6.3.4-1.cdh6.3.4.p0.6751098-el7.parcel]$

The file "CDH-6.3.4-1.cdh6.3.4.p0.6751098-el7.parcel" copied normally from cdh01 server.

But, a few seconds later the file "CDH-6.3.4-1.cdh6.3.4.p0.6751098-el7.parcel" disappear.

I've installed CDH dozens of times with Cloudera Manger. I haven't had any issues with the other servers, but I'm only having these issues with Custer I'm trying to install right now.

Can anyone help me on this issue?

The error comes up at parcel unpacking

[27/Jun/2022 09:45:00 +0900] 22914 WorkerThread parcel_cache INFO Unpacking /data/opt/cloudera/parcels/.flood/CDH-6.3.4-1.cdh6.3.4.p0.6751098-el7.parcel/CDH-6.3.4-1.cdh6.3.4.p0.6751098-el7.parcel into /data/opt/cloudera/parcels

1. Make sure you have enough space left on your hosts even after the parcel is downloaded; more than twice the parcel size for the unpacking to be successful.

2. To verify the same and also check in case the downloaded parcel file is corrupt, try to untar the parcel file on the host to some different location. If there are any of the above issues, this command would fail with appropriate errors.

# tar -xvf CDH-6.3.4-1.cdh6.3.4.p0.6751098-el7.parcel 

clear the untarred contents once you are finished testing to save space.  

Clear the parcel directory, restart the agent and monitor the progress.

Hope this helps,

Hi Paras,

I have enough free space in my server. 

So, I try to untar manually. It works.

Untar parcel file and move to /opt/cloudera/parcels.

And then, Cloudera Manager Agent is automatically recognize the files and it works no problems.

Thank you for your efforts.

Regards,

JinGon.
