Hello Everyone, Has anyone tested the Distcp editor available in HUE with CDP 7.1.5? Currently I see the below screen: In this, I'm not able to manually enter the source cluster path. As soon as I click on the source path text box, it opens a dialog box to select the path from the current cluster HDFS. Has anybody tested pulling data from another cluster? What config changes are required for getting this to work? Thanks, Megh

Added the same configuration in "HDFS Client Advanced Configuration Snippet (Safety Valve) for hdfs-site.xml" section and restarted the cluster and now the issue is resolved. Thanks, Megh

Hello Everyone, We have recently deployed CDP. I need to fetch data from one of my other cluster (HDFS HA-Enabled) to this cluster using distcp. For configuring the remote nameservice in my CDP cluster, I followed the steps given in this link and added the configuration properties to "HDFS Service Advanced Configuration Snippet (Safety Valve) for hdfs-site.xml" section of HDFS configuration in Cloudera Manager. After this, I restarted the services and tried to run the following command from one of my hosts in the cluster: hadoop fs -ls hdfs://<remote-nameservice-name>/ But it throws this error: 21/03/22 13:59:34 WARN fs.FileSystem: Failed to initialize fileystem hdfs://<remote-nameservice-name>/: java.lang.IllegalArgumentException: java.net.UnknownHostException: <remote-nameservice-name>

What might be the reason behind this? Why does Cloudera manager not manage the config change in the back end? . Thanks, Megh

Hello @Atahar , The Vulnerability ID is "http-options-method-enabled". I Don't want to disable HTTP and enable HTTPS, I want to disable "HTTP Options Method". Thanks, Megh

Hi @Atahar , Thanks for your reply. I'm actually looking for a property to disable HTTP options method as this is being flagged as a vulnerability by my internal Security team. Thanks, Megh

Hello Everyone, Is there a reference document for exhaustive list of properties that can be set within ambari.properties? I would like to check whether Ambari has an option for disabling HTTP OPTIONS method. Thanks, Megh

Hi @GangWar , On the node this issue was occuring, somehow the default jdk folder name was java-1.8.0-openjdk-1.8.0.161-0.b14.el7_4.x86_64, so I assumed that it is 1.8.0.161, but after your suggestion I went into the node and issued "java -version" and to my surprise it was indeed openjdk version "1.8.0_252". Following your suggestion has fixed the issue for me. Thanks a lot! Megh

Hello Everyone, I've recently enabled Kerberos in my cluster and since then one of my datanodes is not able to connect to the namenode: I see these entries in the namenode logs: 2021-02-03 12:06:15,699 INFO ipc.Server (Server.java:saslProcess(1573)) - Auth successful for $4E8100-MH1MCLUV65LO@<Realm-Name> (auth:KERBEROS)

Fixed this by changing my hostnames to lowercase. Earlier the hostnames were mixed case and researching online I found that Kerberos expects the hostnames to be lowercase and Realm name to be uppercase. changing the hostnames to all lowercase resolved the issue. Thanks, Megh

Figured out the keytab error. I had changed the encryption types and it was resulting in this error. I reverted those changes in the Kerberos configuration and it came clean. But after the entire process, now the services are not coming up. Firstly, it is getting stuck on starting the namenode, with safe mode not getting turned off automatically. If I leave the namenode manually, then it is showing the below error: stderr:
2021-02-01 17:18:32,891 - The NameNode is still in Safemode. Please be careful with commands that need Safemode OFF.
