Re: Reading configuration file in Spark Scala throws error
OK it turned up pretty simple once I established where to read the conf
file in yarn mode and get the values for different keys
val dbHost = conf.getString("dbHost")
val dbPort = conf.getString("dbPort")
val dbConnection = conf.getString("dbConnection")
val namespace = conf.getString("namespace")
val dbSetRead = conf.getString("dbSetRead")
val dbSetWrite = conf.getString("dbSetWrite")
val dbPassword = conf.getString("dbPassword")
val bootstrapServers = conf.getString("bootstrapServers")
val schemaRegistryURL = conf.getString("schemaRegistryURL")
val zookeeperConnect = conf.getString("zookeeperConnect")
val zookeeperConnectionTimeoutMs =
conf.getString("zookeeperConnectionTimeoutMs")
val rebalanceBackoffMS = conf.getString("zookeeperConnectionTimeoutMs")
val zookeeperSessionTimeOutMs =
conf.getString("zookeeperSessionTimeOutMs")
val autoCommitIntervalMS = conf.getString("autoCommitIntervalMS")
val topicsValue = conf.getString("topicsValue")
val memorySet = conf.getString("memorySet")
val enableHiveSupportValue = conf.getString("enableHiveSupportValue")
val sparkStreamingReceiverMaxRateValue =
conf.getString("sparkStreamingReceiverMaxRateValue")
val checkpointdir = conf.getString("checkpointdir")
val hbaseHost = conf.getString("hbaseHost")
val zookeeperHost = conf.getString("zookeeperHost")
val zooKeeperClientPort = conf.getString("zooKeeperClientPort")
val batchInterval = conf.getInt("batchInterval")
val tickerWatch = conf.getString("tickerWatch")
val priceWatch= conf.getDouble("priceWatch")
val op_type = conf.getInt("op_type")
val currency = conf.getString("currency")
val tickerType = conf.getString("tickerType")
val tickerClass = conf.getString("tickerClass")
val tickerStatus = conf.getString("tickerStatus")
val confidenceLevel = conf.getDouble("confidenceLevel")
var hvTicker = conf.getInt("hvTicker")
Thanks again.

Re: Reading configuration file in Spark Scala throws error
Many thanks Chris.
In my Spark streaming I would like to use the config file to read the
parameters in. Taking your example, I have
val globalConfig = ConfigFactory.load()
val conf = globalConfig.getConfig(sparkAppName) // extract out
top level key from top level namespace
val printEntry = new
java.util.function.Consumer[java.util.Map.Entry[String,com.typesafe.config.ConfigValue]]
{
override def accept(a:
java.util.Map.Entry[String,com.typesafe.config.ConfigValue]): Unit = {
val key = a.getKey
val value = a.getValue.unwrapped
//val value2 = conf.getAnyRef(a.getKey)
println( s"$key = $value")
}
}
conf.entrySet.iterator.forEachRemaining (printEntry)
And my config file for spark is like below
cat md_AerospikeAerospike.conf
md_AerospikeAerospike {
dbDatabase = "trading"
dbPassword = "mongodb"
dbUsername = "trading_user_RW"
bootstrapServers = "rhes75:9092, rhes75:9093, rhes75:9094, rhes564:9092,
rhes564:9093, rhes564:9094, rhes76:9092, rhes76:9093, rhes76:9094"
schemaRegistryURL = "http://rhes75:8081;
zookeeperConnect = "rhes75:2181, rhes564:2181, rhes76:2181"
zookeeperConnectionTimeoutMs = "1"
rebalanceBackoffMS = "15000"
zookeeperSessionTimeOutMs = "15000"
autoCommitIntervalMS = "12000"
topicsValue = "md"
memorySet = "F"
enableHiveSupport = null
enableHiveSupportValue = "true"
sparkStreamingReceiverMaxRateValue = "0"
checkpointdir = "/checkpoint"
mongodbHost = "rhes75"
mongodbPort = "60100"
zookeeperHost = "rhes75"
zooKeeperClientPort = "2181"
batchInterval = 2
tickerWatch = "VOD"
priceWatch = 300.0
op_type = 1
currency = "GBP"
tickerType = "short"
tickerClass = "asset"
tickerStatus = "valid"
}
So I want them to be imported into Spark program.
Using the above println( s"$key = $value"), I get
zookeeperHost = rhes75
zookeeperSessionTimeOutMs = 15000
memorySet = F
topicsValue = md
currency = GBP
rebalanceBackoffMS = 15000
tickerStatus = valid
enableHiveSupportValue = true
autoCommitIntervalMS = 12000
mongodbPort = 60100
bootstrapServers = rhes75:9092, rhes75:9093, rhes75:9094, rhes564:9092,
rhes564:9093, rhes564:9094, rhes76:9092, rhes76:9093, rhes76:9094
zookeeperConnect = rhes75:2181, rhes564:2181, rhes76:2181
zookeeperConnectionTimeoutMs = 1
dbUsername = trading_user_RW
dbPassword = mongodb
tickerWatch = VOD
tickerClass = asset
checkpointdir = /checkpoint
mongodbHost = rhes75
schemaRegistryURL = http://rhes75:8081
tickerType = short
zooKeeperClientPort = 2181
priceWatch = 300
batchInterval = 2
op_type = 1
sparkStreamingReceiverMaxRateValue = 0
dbDatabase = trading
Two things please. They are read in in a different order and secondly *the
String values are not quoted.** like currency = GBP as opposed to currency
= "GBP"*
What would be the easiest way of resolving the above please

Re: Reading configuration file in Spark Scala throws error
This seems to work-
val printEntry = new
java.util.function.Consumer[java.util.Map.Entry[String,com.typesafe.config.ConfigValue]]
{
override def accept(a:
java.util.Map.Entry[String,com.typesafe.config.ConfigValue]): Unit = {
println(a.getKey)
}
}
conf.entrySet.iterator.forEachRemaining (printEntry)
// returns
scala> conf.entrySet.iterator.forEachRemaining (printEntry)
dbUsername
dbPassword
bootstrapServers
dbDatabase
I hope that helps.

Reading configuration file in Spark Scala throws error
Hi,
I have a config file application.conf that I am trying to read.
The skeleton code is as follows:
```
import com.typesafe.config.ConfigFactory
import scala.collection.JavaConverters
def main(args: Array[String]): Unit = {
val globalConfig = ConfigFactory.load() // pass in filename (without
extension) to load additional config file in src/main/resources or CLASSPATH
val conf = globalConfig.getConfig("database") // extract out top
level key from top level namespace
conf.entrySet().iterator().forEachRemaining { entry =>
val key:String = entry.getKey
val value: Any= entry.getValue.unwrapped() // access via entry
val value2: Any= conf.getAnyRef(key) // access via hash
lookup from config
println( s"$key : $value | $value2" ) // string
interpolation
}
}
```
But I am getting the following error
```
[info] Compiling 1 Scala source to
/data6/hduser/scala/testconf/target/scala-2.11/classes...
[error]
/data6/hduser/scala/testconf/src/main/scala/myPackage/testconf.scala:10:
missing parameter type
[error] conf.entrySet().iterator().forEachRemaining { entry =>
[error] ^
[error] one error found
[error] (compile:compileIncremental) Compilation failed
```
The application.conf has the following layout
database = {
dbDatabase = "trading"
dbPassword = "mongodb"
dbUsername = "trading_user_RW"
bootstrapServers = "rhes75:9092"
}
I appreciate any hint
