初始化 SparkContext 时出错

我尝试在 Mac OS Yosemite 10.10.5上使用

"./bin/spark-shell".

它有下面的错误。我还尝试安装不同版本的 Spark，但是所有版本都有相同的错误。这是我第二次管理 Spark 了。我之前的运行工作正常。

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

然后我加上

export SPARK_LOCAL_IP="127.0.0.1"

将错误更改为:

I've built it from the current master branch with version 2.0.0-SNAPSHOT. After adding export SPARK_LOCAL_IP="127.0.0.1" to load-spark-env.sh it worked for me. I'm using Macos 10.10.5. So it could be version issue?

Following steps might help:

  1. Get your hostname by using "hostname" command.

  2. Make an entry in the /etc/hosts file for your hostname if not present as follows: 

    127.0.0.1      your_hostname

Hope this helps!!

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
小开

I always get that when switching between networks. This solves it:

$ sudo hostname -s 127.0.0.1

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);
小开

If you don't want to change the hostname of your Mac, you can do the following:

  1. 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/).
  2. cp spark-env.sh.template spark-env.sh
  3. Add export SPARK_LOCAL_IP=127.0.0.1 under the comment for local IP.

Start spark-shell and enjoy it.

小开

There are two errors I think.

  1. Your spark local ip was not correct and needs to be change to 127.0.0.1.
  2. 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.

小开 
sparkContext = new JavaSparkContext("local[4]", "Appname")


export SPARK_LOCAL_IP=127.0.0.1

just doing above worked for me.

小开

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()

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.

小开 
export SPARK_LOCAL_IP=127.0.0.1

For mac .bash_profile.

小开

In Mac,Check IP in System Preference -> Network -> click the Wifi you are connected(it should show green icon) -> check the IP just above your Network Name.

Make following entry in ../conf/spark-env.sh :

SPARK_MASTER_HOST=<<your-ip>>
SPARK_LOCAL_IP=<<your-ip>>

and than try spark-shell. Doing above changes worked for me.

小开

When ever you will switch network while working with spark, It happens due to network switch. for instant fix you have to add "spark.driver.bindAddress" in "localhost" mode or "127.0.0.1" in your spark application

// Create a SparkContext using every core of the local machine
val confSpark = new SparkConf().set("spark.driver.bindAddress", "localhost")
val sc = new SparkContext("local[*]", "appname", conf = confSpark)
