Re-install a recently uninstalled Hosts fail - unclean remove?

avatar
Explorer

I recently uninstalled a host because I installed the wrong CDH version (5.1.2). I was suppose to install CDH 5.0.3 on the host to match the cluster. I performed a manual yum remove install on the different packages based on this documentation: http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM5/latest/Cloudera-Manager-Installat...

 
Now I try to reinstall the host via Cloudera Manager and then I run into the error below. I think the uninstall was not clean. Anybody have any tips on how to resolve this? Thanks in advance.

Thanks for the reply.

 

I tried the steps you suggested, but the problem still remains.

 

I've solved this solution by trying the following steps provided by JohnKelly of CDH Google Group combined with the CDH uninstall guide:

 

1. Follow this instruction:

 

http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH5/latest/CDH5-Installation-Guide/c...

 

2. I ran the following command (credits to JohnKelly):

 

rpm -e --allmatches $(rpm -qa | grep -e^hadoop -e^cloudera -e^hue -e^oozie -e^hbase -e^impala -e^flume -e^hive)

yum clean all

rm -Rf /usr/share/cmf /var/lib/cloudera* /var/cache/yum/cloudera*

sudo rm -Rf /usr/share/cmf /var/lib/cloudera* /var/cache/yum/cloudera*

rm /tmp/.scm_prepare_node.lock

 

After that everything was good.

​remove those two packages first, then ensure your CDH5 repo points to
5.0.3, not 5 (which will be the latest in 5.x)

# yum remove hadoop hadoop-hdfs
# yum clean all
# yum makecache
# yum list | grep cdh5.1.2 (should not list anything)
