--------------------------------
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}
