Below are the steps I followed for ignite with spark on Yarn but I am stuck
after spending almost all day on this.
- copied apache-ignite-fabric-2.1.0-bin (tried 2.3.0 initially but the
it didnt work) to all the 4 slave nodes of Spark cluster and started ignite
with ./bin/ignite.sh. It shows as given below, after starting
*Topology snapshot [ver=10, servers=4, clients=0, CPUs=32, heap=4.0GB]*
- updated the spark-env.sh on all slave nodes with IGNITE_HOME and class
paths as below
IGNITE_HOME=/home/ec2-user/rchalil/apache-ignite-fabric-2.1.0-bin
IGNITE_LIBS="${IGNITE_HOME}/libs/*"
for file in ${IGNITE_HOME}/libs/*
do
if [ -d ${file} ] && [ "${file}" != "${IGNITE_HOME}"/libs/optional ];
then
IGNITE_LIBS=${IGNITE_LIBS}:${file}/*
fi
done
export spark.driver.extraClassPath=$IGNITE_LIBS
export spark.executor.extraClassPath=$IGNITE_LIBS
- updated the default config.xml as attached with the static ips
- On the Spark Master node (Only), added the - <property name=
"clientMode" value="true"/>
In the simple test code, i tried 2 things, both without success:
1. Added config/default-config.xml directly under the project and added the
below snippet.
val CONFIG = "config/default-config.xml"
val igniteContext = new IgniteContext(sparkContext, CONFIG, true)
val sharedRDD: IgniteRDD[Int, Int] = igniteContext.fromCache[Int,
Int]("sharedRDD")
sharedRDD.savePairs(sparkContext.parallelize(1 to 100000, 10).map(i => (i, i)))
sharedRDD.mapValues(x => (x * x))
During execution, it complains that - class
org.apache.ignite.IgniteCheckedException:
Spring XML configuration path is invalid: config/default-config.xml. Note
that this path should be either absolute or a relative local file system
path, relative to META-INF in classpath or valid URL to IGNITE_HOME.
2. Commented the above snippet and used the below:
val ic = new IgniteContext(sparkContext, () => new IgniteConfiguration())
val sharedRDD: IgniteRDD[Int, Int] = ic.fromCache("partitioned")
sharedRDD.savePairs(sparkContext.parallelize(1 to 100000, 10).map(i => (i, i)))
Now it complains that "it cannot find any IPs from multicast or IPFinder.
Not sure what am i doing not right. I also have a cluster.properties file
but I am not sure if it is needed for the yarn setup and I am not
explicitly calling it anywhere. Thank you.
