[apache-spark] Mac Spark-shell 오류 초기화 SparkContext

Question 1

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).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

                ^
<console>:16: error: not found: value sqlContext
         import sqlContext.sql

그런 다음 추가

export SPARK_LOCAL_IP="127.0.0.1"

spark-env.sh로 오류가 다음과 같이 변경됩니다.

 ERROR : No route to host
    java.net.ConnectException: No route to host

       import sqlContext.sql

Question 2

다음 단계가 도움이 될 수 있습니다.

“hostname”명령을 사용하여 호스트 이름을 가져옵니다.
호스트 이름이 없으면 다음과 같이 / etc / hosts 파일에 항목을 만듭니다.
```
127.0.0.1      your_hostname
```

도움이 되었기를 바랍니다!!

Question 3

나는 항상 네트워크 사이를 전환 할 때 그것을 얻습니다. 이것은 그것을 해결합니다 :

$ sudo hostname -s 127.0.0.1

Question 4

현재 마스터 브랜치에서 version 2.0.0-SNAPSHOT. 추가 한 후 export SPARK_LOCAL_IP="127.0.0.1"에 load-spark-env.sh나를 위해 일했다. Macos 10.10.5를 사용하고 있습니다. 그래서 버전 문제일까요?

Question 5

spark.driver.hostIDE를 사용하는 경우을 로컬 호스트로 설정하십시오.

SparkConf conf = new  SparkConf().setMaster("local[2]").setAppName("AnyName").set("spark.driver.host", "localhost");
JavaSparkContext sc = new JavaSparkContext(conf);

Question 6

제 생각에는 두 가지 오류가 있습니다.

스파크 로컬 IP가 올바르지 않아 127.0.0.1로 변경해야합니다.
sqlContext를 올바르게 정의하지 않았습니다.

1. 나는 시도했다 :

1) ~ / .bash_profile에 SPARK_LOCAL_IP = “127.0.0.1”을 내보냈습니다.
2) $ SPARK_HOME 아래 load-spark-env.sh에 내보내기 SPARK_LOCAL_IP = “127.0.0.1”추가

그러나 둘 다 작동하지 않았습니다. 그런 다음 다음을 시도했는데 효과가 있습니다.

val conf = new SparkConf().
    setAppName("SparkExample").
    setMaster("local[*]").
    set("spark.driver.bindAddress","127.0.0.1")
val sc = new SparkContext(conf)

2. 시도해 볼 수 있습니다.

sqlContext = SparkSession.builder.config("spark.master","local[*]").getOrCreate()

그리고 import sqlContext.implicits._

SparkSession의 빌더는 SparkContext가 있으면 자동으로 사용하고, 그렇지 않으면 생성합니다. 필요한 경우 명시 적으로 두 개를 만들 수 있습니다.

Question 7

Mac의 호스트 이름을 변경하지 않으려면 다음을 수행 할 수 있습니다.

spark-env.sh.template컴퓨터 에서 템플릿 파일 을 찾습니다 (아마도 /usr/local/Cellar/apache-spark/2.1.0/libexec/conf/).
cp spark-env.sh.template spark-env.sh
export SPARK_LOCAL_IP=127.0.0.1로컬 IP에 대한 주석 아래에 추가하십시오 .

시작 spark-shell하고 즐기십시오.

Question 8

Scala를 사용하여 IDE에서 코드를 실행하고 동일한 문제가 발생하고 위에서 지적한대로 SparkConf ()를 사용하지 않고 SparkSession ()을 사용하는 경우 다음과 같이 로컬 호스트 주소를 바인딩 할 수 있습니다. SparkConf ()에서. .config ()를 사용하여 아래와 같이 스파크 구성을 설정해야합니다.

    val spark = SparkSession
       .builder()
       .appName("CSE512-Phase1")
       .master("local[*]").config("spark.driver.bindAddress", "localhost")
       .getOrCreate()
