We have found out that MSFT has also released a fix for the Kerberos authentication issue. To fix the Windows AD, you can engage with the AD team to apply one of the following patches that MSFT has provided to fix the Kerberos authentication issue. Please link on the appropriate link based on the flavor of the Windows Server.

Community support is the only free support option. You could reach out to Cloudera to get the cluster under support or roll back the change on the AD side. BTW, CDH 5 is reaching end of support (EOS) on Dec 31 so you'd need to upgrade to CDH 6 or CDP. Both of these will require a license for the most recent versions.

CDW cannot use GreenPlum as a DW DB. You could ingest data from GreenPlum into the cluster and use Hive/Impala from CDW.

This is likely caused by a change in your AD servers. The CVE is CVE-2020-17049 You'll need to file a case with Support and get a patch.

I think you want to put the result set getWarnings() inside the while loop. while(rs.next()){ System.out.println(rs.getInt("id")); if (rs.getWarnings() != null ) { System.out.println(rs.getWarnings()); System.out.println(rs.clearWarnings()); } } According to the JDBC ResultSet docs, ResultSet warnings are set for each row when you call a method on the ResultSet which you haven't done yet in your current code. Also, warnings on multiple rows are appended which is why I added the clearWarning().

As a best practice, you should enable HDFS HA to avoid a single point of failure.

That's way too general a question to provide a useful response. Give us some background like: 1.Overview of the cluster config including CDH/HDP version, if HA is enabled 2. Any recent changes 3. Errors/Exceptions in the NN log files

IIRC, The ImpalaD process runs as the "impala". If you have sentry grants that enable access to roles the user is in any HDFL ACLs to the contrary will be ignored. The proper way to do this is to use Sentry to grant access to the roles which map to groups and users, you want to have access and then enable HDFS ACLs to sync the HDFS access.
