In my case, though DistCp editor didn't work out, this same thing could be achieved within HUE by using DistCp action in Oozie. Designed a simple oozie workflow with DistCp action and managed to get it working. Thanks, Megh

Hi Gangwar, Thanks for your reply, we're using CDH6.3.2, it means that we can use Digest authentication to reduce the risk from this CVE?

@PrernaU You can check if ipc.client.fallback-to-simple-auth-allowed to true in core-site.xml and see if that helps.

@ateka_18 The downtime is better choice because KTS interacts with CDH cluster and failure/Down of KTS will hamper the CDH services hence the job.

@bsaad On computer there is no way to increase the RAM until you have physical memory available. In cloud you can build any large machine or extend the RAM if that helps.

I have found the cause, it seems that Cloudera always use the /etc/krb5.conf file, if fact, if I changed this file to restrict the algoriths, Cloudera would not get up; but for jobs running inside Cloudera, it looks for /etc/krb5/krb5.conf file, once I created this file and add the following line to it, it started to work properly: allow_weak_crypto = true Note: It was needed to remove "MD5" from jdk.tls.disabledAlgorithms y java.security.

Hi @JGUI , There is no requirement for deleting the data from the datanode that is going to be decommissioned. Once the DN is been decommissioned all the blocks in the DN would be replicated to a different DN. And is there any error that you are encountering while you are decommissioning ? Typically, HDFS would self-heal and would re-replicate the under-replicated blocks that are due to the DN that is been decommissioned. And NN would start replicating the blocks with the other two replication that is present in HDFS.

@bobreynolds The service keytabs by default is in /var/run/cloudera-scm-agent/process/xxx-flume-xxxx . Hope you are checking in the same dir. If it's not there then you probably have to generate missing credentials from CM > Administration > Security > Kerberos Credentials and then regenerate.
