             Summary: Gobblin kerberos token management for multiple remote hive metastores
                 Key: GOBBLIN-1398
                 URL: https://issues.apache.org/jira/browse/GOBBLIN-1398
             Project: Apache Gobblin
          Issue Type: Improvement
    Affects Versions: 0.15.0
            Reporter: Jay Sen
             Fix For: 0.16.0


Gobblin's hadoop tokens/ key management : 
 Problem: Gobblin only maintains local cluster tokens when key management is enabled. and does not have capability to manage tokens for remote hadoop cluster. ( based on my conversation with many folks here, the token files can be made available externally. but that would require that external system running on cron or something )

Solution: add remote cluster token management in Gobblin. where remote clusters key can be managed same way it manages the local clusters keys.

 

Config looks like following

( Changes the enable.key.management config to key.management.enabled )

 
{code:java}
gobblin.hadoop.key.management {
 enabled = true
 remote.clusters = [ ${gobblin_sync_systems.hadoop_cluster1}, ${gobblin_sync_systems.hadoop_cluster2} ]
}

// These Gobblin platform configurations can be moved to database for other use-cases, but this layout helps make the platform moduler for each connectors.
gobblin_sync_systems {
 hadoop_cluster1 {
 // if Hadoop config path is specified, the FileSystem will be created based on all the xml config provided here, which has all the required info.
 hadoop_config_path = "file:///etc/hadoop_cluster1/hadoop/config"
 // If hadoop config path is not specified, you can still specify the speecific nodes for the specific type of tokens
 namenode_uri = ["hdfs://nn1.hadoop_cluster1.example.com:8020", "hdfs://nn2.hadoop_cluster1.example.com:8020"]
 kms_nodes = [ "kms1.hadoop_cluster1.example.com:9292", "kms2.hadoop_cluster1.example.com:9292" ]
 }
 hadoop_cluster2 {
 hadoop_config_path = "file:///etc/hadoop_cluster1/hadoop/config"
 namenode_uri = ["hdfs://nn1.hadoop_cluster2.example.com:8020", "hdfs://nn2.hadoop_cluster2.example.com:8020"]
 kms_nodes = [ "kms1.hadoop_cluster2.example.com:9292", "kms2.hadoop_cluster2.example.com:9292" ]
 }
}{code}
