RangerAdminRESTClient: Error getting Roles - apache-spark

I'm trying to connect my apache spark to apache Ranger using Spark AuthZ Plugin.
Kerberos is enabled for both spark and apache ranger .
i'm getting this error "WARN RangerAdminRESTClient: Error getting Roles. secureMode=true, user=hive/host_fqdn#MYCOMPANY.COM (auth:KERBEROS), response={"httpStatusCode":401,"statusCode":0}, serviceName=hive_policy"

spark ETL and spark thrift server

Some details:
Spark SQL (version 3.2.1)
Driver: Hive JDBC (version 2.3.9)
ThriftCLIService: Starting ThriftBinaryCLIService on port 10000 with 5...500 worker threads
BI tool is connect via odbc driver
After activating Spark Thrift Server I'm unable to run pyspark script using spark-submit as they both use the same metastore_db
error:
Caused by: ERROR XJ040: Failed to start database 'metastore_db' with class loader org.apache.spark.sql.hive.client.IsolatedClientLoader$$anon$1#3acaa384, see the next exception for details.
at org.apache.derby.iapi.error.StandardException.newException(Unknown Source)
at org.apache.derby.impl.jdbc.SQLExceptionFactory.wrapArgsForTransportAcrossDRDA(Unknown Source)
... 140 more
Caused by: ERROR XSDB6: Another instance of Derby may have already booted the database /tmp/metastore_db.
I need to be able to run PySpark (Spark ETL) while having spark thrift server up for BI tool queries.
Any workaround for it?
Thanks!
In my case the solution was to move the metastore_db to a database server like MySql (in my case) or Postgresql.
You will have to configure $SPARK_HOME/conf/hive-site.xml and include your jdbc driver in $SPARK_HOME/jars path

Make Spark application use all available YARN resources

I am currently using a cluster of 5 Raspberry Pi 4 (4GB) and I installed Hadoop to manage the resources. Unfortunately I am not able to config the settings right to use the full resources (4 worker nodes, 1 master node) for the Apache Spark Application, which I submit on top of the Hadoop Framework.
Does somebody knows, how I have to config the settings right to use the full resources (16 cores, 14 GB RAM) for only 1 application?
My current settings are:

YARN nodemanager error while running basic sparkpi example

I am running a basic spark program to test my YARN setup with Spark. I am running a job similar to the example one on the website.
spark-submit --master yarn --deploy-mode cluster --num-executors 75 --
executor-cores 2 --executor-memory 6g --class
org.apache.spark.examples.JavaSparkPi
/home/spark/examples/jars/spark_examples.jar 1000
However, the job never terminates and the nodemanagers on the different nodes show this error:
2020-03-16 14:27:42,917 WARN org.apache.hadoop.yarn.server.nodemanager.containermanager.ContainerManagerImpl: couldn't find container container_1584386586744_0001_01_000319 while processing FINISH_CONTAINERS event
I am not sure whats causing this. Any advice is appreciated.

Query hive database using hive context created on spark 2.3.0

I am able to create a hive context programmatically on spark 1.6.0 using :
val conf = new SparkConf().setAppName("SparkTest").setMaster("local")
val sc=new SparkContext(conf)
val hc = new HiveContext(sc)
val actualRecordCountHC = hc.sql("select count(*) from hiveorc_replica.appointment")
This is working fine for me.
In the same way, I want to create a hive context on spark 2.3.0 but when running the program, it throws the following error:
org.apache.spark.sql.AnalysisException:
Table or view not found: `hiveorc_replica`.`appointment`; line 1 pos 21;
'Aggregate [unresolvedalias(count(1), None)]
'UnresolvedRelation `hiveorc_replica`.`appointment`
I know that HiveContext(sc) has been deprecated in 2.3.0 but when run these as commands on spark-shell, they are also giving results. Also, I want to make the program generic for both versions of spark. Can someone please suggest some way of querying hive tables directly without using the hive database file names ?
Following is the hive-site.xml I am using to connect remotely-
<?xml version="1.0" encoding="UTF-8"?>

Here, fqdn is being replaced by the host hdfs FQDN during run time and is running perfectly for spark 1.6.0.
In spark 2.x.x you need to use enableHiveSupport() when creating SparkSession
val spark = SparkSession.builder()
.appName("Example")
.master("local")
.config("hive.metastore.uris","thrift://B:PortNumber")
.enableHiveSupport() // <---- This line here
.getOrCreate()
And if you want generic - I think you just need to create SparkContext and HiveContext separately:
if (sparkVersion <= 2.x.x) {
// create the old way
}
else
{
//create spark session and then get SparkContext and HiveContext from it.
}
Here you can find how to know spark version programmatically

How to encrypt and decrypt Azure Storage Access Key

I have created Azure VM and installed my Java application in it and then connected to WASB storage.
I have added following jars and core-site.xml to access WASB storage from Java application.
azure-storage
hadoop-azure
core-site.xml
<configuration>
<property>
<name>fs.AbstractFileSystem.wasb.impl</name>
<value>org.apache.hadoop.fs.azure.Wasb</value>
</property>
<property>
<name>fs.azure.account.key.STORAGE_ACCOUNT_NAME .blob.core.windows.net</name>
<value>STORAGE ACCESS KEY</value>
</property>
<property>
<name>fs.azure.io.copyblob.retry.max.retries</name>
<value>60</value>
</property>
<property>
<name>fs.azure.io.read.tolerate.concurrent.append</name>
<value>true</value>
</property>
<property>
<name>fs.azure.page.blob.dir</name>
<value>/mapreducestaging,/atshistory,/tezstaging,/ams/hbase/WALs,/ams/hbase/oldWALs,/ams/hbase/MasterProcWALs</value>
</property>
<property>
<name>fs.defaultFS</name>
<value>wasb://STORAGE_CONTAINER_NAME#STORAGE_ACCOUNT_NAME.blob.core.windows.net</value>
<final>true</final>
</property>
<property>
<name>fs.trash.interval</name>
<value>360</value>
</property>
</configuration>
I have used Storage Access Key directly in core-site.xml. But I want Access key to be encrypted.
When I search about it, I got to know about below script:-
<property>
<name>fs.azure.account.keyprovider.youraccount</name>
<value>org.apache.hadoop.fs.azure.ShellDecryptionKeyProvider</value>
</property>
<property>
<name>fs.azure.account.key.youraccount.blob.core.windows.net</name>
<value>YOUR ENCRYPTED ACCESS KEY</value>
</property>
<property>
<name>fs.azure.shellkeyprovider.script</name>
<value>PATH TO DECRYPTION PROGRAM</value>
</property>
How do I access WASB storage with encrypted key. Is there a sample available for it for above configuration ?
Note:- I am connecting Azure VM directly to WASB storage without using HDInsight Cluster.
KeyVault maybe the best choice for you to store the secret - keys.
