One question / kerberos, yarn-cluster -> connection to hbase

[sudhir37]

Facing one issue with Kerberos enabled Hadoop/CDH cluster.
 
We are trying to run a streaming job on yarn-cluster, which interacts with
Kafka (direct stream), and hbase.
 
Somehow, we are not able to connect to hbase in the cluster mode. We use
keytab to login to hbase.
 
This is what we do:
spark-submit --master yarn-cluster --keytab "dev.keytab" --principal
"d...@io-int.com"  --conf
"spark.executor.extraJavaOptions=-Dlog4j.configuration=log4j_executor_conf.properties
-XX:+UseG1GC" --conf
"spark.driver.extraJavaOptions=-Dlog4j.configuration=log4j_driver_conf.properties
-XX:+UseG1GC" --conf spark.yarn.stagingDir=hdfs:///tmp/spark/ --files
"job.properties,log4j_driver_conf.properties,log4j_executor_conf.properties"
service-0.0.1-SNAPSHOT.jar job.properties
 
To connect to hbase:
 def getHbaseConnection(properties: SerializedProperties): (Connection,
UserGroupInformation) = {
 
   
val config = HBaseConfiguration.create();
config.set("hbase.zookeeper.quorum", HBASE_ZOOKEEPER_QUORUM_VALUE);
config.set("hbase.zookeeper.property.clientPort", 2181);
config.set("hadoop.security.authentication", "kerberos");
config.set("hbase.security.authentication", "kerberos");
config.set("hbase.cluster.distributed", "true");
config.set("hbase.rpc.protection", "privacy");
   config.set("hbase.regionserver.kerberos.principal",
“hbase/_h...@io-int.com”);
config.set("hbase.master.kerberos.principal", “hbase/_h...@io-int.com”);
 
UserGroupInformation.setConfiguration(config);
 
 var ugi: UserGroupInformation = null;
  if (SparkFiles.get(properties.keytab) != null
&& (new java.io.File(SparkFiles.get(properties.keytab)).exists)) {
ugi =
UserGroupInformation.loginUserFromKeytabAndReturnUGI(properties.kerberosPrincipal,
  SparkFiles.get(properties.keytab));
  } else {
ugi =
UserGroupInformation.loginUserFromKeytabAndReturnUGI(properties.kerberosPrincipal,
  properties.keytab);
  }
   
 
val connection = ConnectionFactory.createConnection(config);
return (connection, ugi);
  }
 
and we connect to hbase:
 ….foreachRDD { rdd =>
  if (!rdd.isEmpty()) {
//var ugi: UserGroupInformation =
Utils.getHbaseConnection(properties)._2
rdd.foreachPartition { partition =>
  val connection = Utils.getHbaseConnection(propsObj)._1
  val table = …
  partition.foreach { json =>
   
  }
  table.put(puts)
  table.close()
  connection.close()
}
  }
}
 
 
Keytab file is not getting copied to yarn staging/temp directory, we are not
getting that in SparkFiles.get… and if we pass keytab with --files,
spark-submit is failing because it’s there in --keytab already.

What version of Spark are you using?  Can you provide your logs with DEBUG
logging enabled?  You should see these logs:
https://github.com/apache/spark/blob/master/resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/Client.scala#L475

One question / kerberos, yarn-cluster -> connection to hbase

[Sudhir Jangir]

Facing one issue with Kerberos enabled Hadoop/CDH cluster.

 

We are trying to run a streaming job on yarn-cluster, which interacts with 
Kafka (direct stream), and hbase. 

 

Somehow, we are not able to connect to hbase in the cluster mode. We use keytab 
to login to hbase. 

 

This is what we do:

spark-submit --master yarn-cluster --keytab "dev.keytab" --principal 
"d...@io-int.com"  --conf 
"spark.executor.extraJavaOptions=-Dlog4j.configuration=log4j_executor_conf.properties
 -XX:+UseG1GC" --conf 
"spark.driver.extraJavaOptions=-Dlog4j.configuration=log4j_driver_conf.properties
 -XX:+UseG1GC" --conf spark.yarn.stagingDir=hdfs:///tmp/spark/ --files 
"job.properties,log4j_driver_conf.properties,log4j_executor_conf.properties" 
service-0.0.1-SNAPSHOT.jar job.properties

 

To connect to hbase:

 def getHbaseConnection(properties: SerializedProperties): (Connection, 
UserGroupInformation) = {

 

   

val config = HBaseConfiguration.create();

config.set("hbase.zookeeper.quorum", HBASE_ZOOKEEPER_QUORUM_VALUE);

config.set("hbase.zookeeper.property.clientPort", 2181);

config.set("hadoop.security.authentication", "kerberos");

config.set("hbase.security.authentication", "kerberos");

config.set("hbase.cluster.distributed", "true");

config.set("hbase.rpc.protection", "privacy");

   config.set("hbase.regionserver.kerberos.principal", 
“hbase/_h...@io-int.com”);

config.set("hbase.master.kerberos.principal", “hbase/_h...@io-int.com”);

 

UserGroupInformation.setConfiguration(config);

  

 var ugi: UserGroupInformation = null;

  if (SparkFiles.get(properties.keytab) != null

&& (new java.io.File(SparkFiles.get(properties.keytab)).exists)) {

ugi = 
UserGroupInformation.loginUserFromKeytabAndReturnUGI(properties.kerberosPrincipal,

  SparkFiles.get(properties.keytab));

  } else {

ugi = 
UserGroupInformation.loginUserFromKeytabAndReturnUGI(properties.kerberosPrincipal,

  properties.keytab);

  }



 

val connection = ConnectionFactory.createConnection(config);

return (connection, ugi);

  }

 

and we connect to hbase:

 ….foreachRDD { rdd =>

  if (!rdd.isEmpty()) {

//var ugi: UserGroupInformation = 
Utils.getHbaseConnection(properties)._2

rdd.foreachPartition { partition =>

  val connection = Utils.getHbaseConnection(propsObj)._1

  val table = … 

  partition.foreach { json =>



  }

  table.put(puts)

  table.close()

  connection.close()

}

  }

}

 

 

Keytab file is not getting copied to yarn staging/temp directory, we are not 
getting that in SparkFiles.get… and if we pass keytab with --files, 
spark-submit is failing because it’s there in --keytab already. 

 

Thanks,

Sudhir
