What's the correct configuration for the Delta Lake connector when the files are stored in Kerberos-secured HDFS? #21979

Closed orthoxerox closed 3 months ago

orthoxerox commented 8 months ago

Describe the problem you faced

Environment Description

Steps To Reproduce

Steps to reproduce the behavior:

  1. Have an on-prem Hadoop cluster with Kerberos authentication
  2. Create Hive and Delta Lake connectors as shown above
  3. Create a Delta Lake table on the cluster
  4. Try querying the created table

Expected behavior

Presto returns the contents of the table

Additional context

The keytab we use looks like this:

ktutil:  read_kt /etc/security/keytabs/hive.service.keytab
ktutil:  l -e
slot KVNO Principal
---- ---- ---------------------------------------------------------------------
   1    1 hive/presto-coordinator.intranet@INTRANET (aes128-cts-hmac-sha1-96)
   2    1 hive/presto-coordinator.intranet@INTRANET (aes256-cts-hmac-sha1-96)
   3    1 hive/presto-coordinator.intranet@INTRANET (arcfour-hmac)
   4    1 hive/presto-coordinator.intranet@INTRANET (camellia256-cts-cmac)
   5    1 hive/presto-coordinator.intranet@INTRANET (camellia128-cts-cmac)

Hi @orthoxerox, to confirm, both hive and delta catalogs are connecting to the same Hadoop Cluster?

orthoxerox commented 8 months ago

Hi @imjalpreet, yes, it's the same Hadoop cluster.

zhongtiancai commented 4 months ago

I got the same Exception when use hudi connector in 0.286

connector.name=hudi hive.config.resources=/etc/hadoop/conf/hive-site.xml,/etc/hadoop/conf/hdfs-site.xml hive.metastore.uri=thrift://host:9083 hive.metastore.authentication.type=KERBEROS hive.metastore.service.principal=hive/_HOST@A.COM hive.metastore.client.principal=user1 hive.metastore.client.keytab=/etc/security/keytabs/user.keytab hive.hdfs.authentication.type=KERBEROS hive.hdfs.impersonation.enabled=true hive.hdfs.presto.principal=user1 hive.hdfs.presto.keytab=/etc/security/keytabs/user.keytab

agrawalreetika commented 4 months ago

@zhongtiancai Can you check once if your above configuration are working fine when you are connecting to hive connector? And to confirm you have placed the required /etc/krb5.conf on the coordinator host as well?

zhongtiancai commented 4 months ago

@agrawalreetika It can display Hive meta information, such as table information, but cannot access HDFS. and the /etc/krb5.conf is also added to the jvm config.

agrawalreetika commented 4 months ago

@zhongtiancai Could you please reach out to me over slack? needed some more setup information.

zhongtiancai commented 4 months ago

@agrawalreetika The program is deployed in the company and cannot connect to the Internet. I tried change the connector from hudi to hive-hadoop2, and it can connect to HDFS normally. But hudi connector will first warn gss initialized fail, and then report 'Could not check if {path} is a valid table'.
I will try reading the source code and more documents to see if I have configured it incorrectly. Then provide feedback here

zhongtiancai commented 3 months ago

@agrawalreetika I solved the problem by delete the code on the krb5. conf file #includedir /etc/krb5.conf.d/ . Because the default_ccached name is configured in this directory and KCM is used, this configuration may cause errors when uses Hadoop
