Hi, What is the version of CDP you are using. Have you restarted the Cloudera Manager server as documented here along with "Test Connection to verify whether the LDAP information you have provided is valid."

Hi @JiHoone Spark security vulnerability CVE-2022-33891 affects Spark 2 and Spark 3 versions but not 3.1.3, 3.0.4, 3.3.0, 3.2.2 versions". The CVE is only affected if you have enabled ACLs on the SHS UI. By default, ACLs are disabled. If ACLs are enabled, then specified users and groups have access, and group membership is checked using ShellBasedGroupsMappingProvider (which is the class with the vulnerability). Cluster is affected by the CVE only when the GroupMappingServiceProvider is called - which means when spark.history.ui.acls.enable or spark.acls.enable is enabled.

Hi @Krisssh 1. '/hbase' is a hbase.root directory 2. The steps should work for HDP3 to CDP, I haven't checked for HDP2 to CDP. There are few known issues when migrating phoenix tables from HDP2 to CDP and it should follow a path HDP2=> HDP3 => CDP. For Hbase tables, as per this it has worked. -- Was your question answered?

Hello @Krisssh , I don't think there should be any challenge exporting the snapshot from CDH5 to CDH6 just like we export it to CDP. So I believe the solution here is not very accurate when it comes to exporting snapshot between major versions. 0) Cluster versions
$ hbase version
HBase 1.2.0-cdh5.17.0-SNAPSHOT
$ hbase version
HBase 2.1.0-cdh6.3.2
0.1) Make sure there's no inconsistencies reported for the target table
1) Take a snapshot in C5
hbase> count 'cluster_test'
100000 row(s) in 16.2700 seconds
hbase> snapshot 'cluster_test', 'cluster_test-ss1'
2) Run the ExportSnapshot tool in C5
$ hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot cluster_test-ss1 -copy-to hdfs://host-10-17-xx.xx:8020/hbase
3) Clone the snapshot in C6
hbase> list_snapshots <=== returns available snapshots
hbase> clone_snapshot 'cluster_test-ss1','cluster_test-new'
4) Confirm the data in C6
hbase> count 'cluster_test-new'
100000 row(s)
5) Run major compaction against the cloned table in C6H

Hello @Krisssh Yes, You can perform an export_snapshot from CDH 5 to CDP 7. In CDH5, the default Hfiles version is 2 and in CDP, it's 3. So the snapshotted files will remain in version 2 in CDP and when the tables are restored from the snapshot, the snapshot will gradually have the snapshot files rewritten into Version 3 files, as the new data is ingested and compactions will rewrite data originally in the snapshot Version 2 file into the new Version 3 files for the table.

Hi @Big-dAta A simple test would be a ping test from the source node to the target node. #ping <ip-address-of-target-node> You can also use Telnet to check if the other node is listening on a specific port. # telnet <ip-address-of-target-node> <port>

Hi, If this is not working from any of the hosts, I believe you need to try the below URLs for 3.1.0 https://docs.cloudera.com/HDPDocuments/Ambari-2.7.3.0/bk_ambari-installation/content/hdp_31_repositories.html Just please bear in mind that the repositories are now behind a paywall, for which you'll have to provide credentials. https://www.cloudera.com/downloads/paywall-expansion.html
