Mac Spark-shell 오류 초기화 SparkContext
Mac OS Yosemite 10.10.5에서 spark 1.6.0 (spark-1.6.0-bin-hadoop2.4)을 시작하려고했습니다.
"./bin/spark-shell".
아래와 같은 오류가 있습니다. 또한 다른 버전의 Spark를 설치하려고 시도했지만 모두 동일한 오류가 있습니다. Spark를 실행하는 것은 이번이 두 번째입니다. 내 이전 실행이 잘 작동합니다.
log4j:WARN No appenders could be found for logger (org.apache.hadoop.metrics2.lib.MutableMetricsFactory).

그런 다음 추가

다음 단계가 도움이 될 수 있습니다.
"hostname"명령을 사용하여 호스트 이름을 가져옵니다.
다음과 같이 호스트 이름이없는 경우 / etc / hosts 파일에 항목을 작성하십시오.
127.0.0.1 your_hostname
도움이 되었기를 바랍니다!!
나는 항상 네트워크 사이를 전환 할 때 그것을 얻습니다. 이것은 그것을 해결합니다 :
$ sudo hostname -s 127.0.0.1
현재 마스터 브랜치에서 version 2.0.0-SNAPSHOT
. 추가 한 후 export SPARK_LOCAL_IP="127.0.0.1"
에 load-spark-env.sh
나를 위해 일했다. Macos 10.10.5를 사용하고 있습니다. 그래서 버전 문제일까요?
Just set the spark.driver.host
to be your localhost if you use IDE
SparkConf conf = new SparkConf().setMaster("local[2]").setAppName("AnyName").set("spark.driver.host", "localhost");
JavaSparkContext sc = new JavaSparkContext(conf);
There are two errors I think.
- Your spark local ip was not correct and needs to be change to 127.0.0.1.
- You didn't difine sqlContext properly.
For 1. I tried:
- 1) exported SPARK_LOCAL_IP="127.0.0.1" in ~/.bash_profile
- 2) added export SPARK_LOCAL_IP="127.0.0.1" in load-spark-env.sh under $SPARK_HOME
But neither worked. Then I tried the following and it worked:
val conf = new SparkConf().
setAppName("SparkExample").
setMaster("local[*]").
set("spark.driver.bindAddress","127.0.0.1")
val sc = new SparkContext(conf)
For 2. you can try:
sqlContext = SparkSession.builder.config("spark.master","local[*]").getOrCreate()
and then import sqlContext.implicits._
The builder in SparkSession will automatically use the SparkContext if it exists, otherwise it will create one. You can explicitly create two if necessary.
If you don't want to change the hostname of your Mac, you can do the following:
- Find the template file
spark-env.sh.template
on your machine (It is probably in/usr/local/Cellar/apache-spark/2.1.0/libexec/conf/
). cp spark-env.sh.template spark-env.sh
- Add
export SPARK_LOCAL_IP=127.0.0.1
under the comment for local IP.
Start spark-shell
and enjoy it.
Sometimes firewall prevents creating and binding a socket. make sure that your firewall is not enable and also you have to check the ip of your machine in /etc/hosts and make sure it's OK then try again:
sudo ufw disable
sparkContext = new JavaSparkContext("local[4]", "Appname")
export SPARK_LOCAL_IP=127.0.0.1
just doing above worked for me.
This happens when you switched between different networks(VPN - PROD, CI based on your company networks to access different environments).
I had the same issue, whenever I switch the VPN.
update sudo /etc/hosts with the hostname value on your Mac.
Just added: export SPARK_LOCAL_IP=127.0.0.1
(for mac .bash_profile)
If you are using Scala to run the code in an IDE, and if you face the same issue and you are not using SparkConf() as pointed out above and using SparkSession() then you could bind the localhost address as follows as set only works in SparkConf(). You should use .config() to set the spark configuration as shown below:
val spark = SparkSession
.builder()
.appName("CSE512-Phase1")
.master("local[*]").config("spark.driver.bindAddress", "localhost")
.getOrCreate()
