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 = $value")
}
}
conf.entrySet.iterator.forEachRemaining (printEntry)
And my config file for spark is like below
cat md_AerospikeAerospike.conf
md_AerospikeAerospike {
dbDatabase = "trading"
dbPassword = "mongodb"
dbUsername = "trading_user_RW"
bootstrapServers = "rhes75:9092, rhes75:9093, rhes75:9094, rhes564:9092,
rhes564:9093, rhes564:9094, rhes76:9092, rhes76:9093, rhes76:9094"
schemaRegistryURL = "http://rhes75:8081";
zookeeperConnect = "rhes75:2181, rhes564:2181, rhes76:2181"
zookeeperConnectionTimeoutMs = "10000"
rebalanceBackoffMS = "15000"
zookeeperSessionTimeOutMs = "15000"
autoCommitIntervalMS = "12000"
topicsValue = "md"
memorySet = "F"
enableHiveSupport = null
enableHiveSupportValue = "true"
sparkStreamingReceiverMaxRateValue = "0"
checkpointdir = "/checkpoint"
mongodbHost = "rhes75"
mongodbPort = "60100"
zookeeperHost = "rhes75"
zooKeeperClientPort = "2181"
batchInterval = 2
tickerWatch = "VOD"
priceWatch = 300.0
op_type = 1
currency = "GBP"
tickerType = "short"
tickerClass = "asset"
tickerStatus = "valid"
}
So I want them to be imported into Spark program.
Using the above println( s"$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 = 10000
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
