scala - How to use s3 with Apache spark 2.2 in the Spark shell

Question

I'm trying to load data from an Amazon AWS S3 bucket, while in the Spark shell.

I have consulted the following resources:

Parsing files from Amazon S3 with Apache Spark

How to access s3a:// files from Apache Spark?

Hortonworks Spark 1.6 and S3

Cloudera

Custom s3 endpoints

I have downloaded and unzipped Apache Spark 2.2.0. In conf/spark-defaults I have the following (note I replaced access-key and secret-key):

spark.hadoop.fs.s3a.impl=org.apache.hadoop.fs.s3a.S3AFileSystem
spark.hadoop.fs.s3a.access.key=access-key 
spark.hadoop.fs.s3a.secret.key=secret-key

I have downloaded hadoop-aws-2.8.1.jar and aws-java-sdk-1.11.179.jar from mvnrepository, and placed them in the jars/ directory. I then start the Spark shell:

bin/spark-shell --jars jars/hadoop-aws-2.8.1.jar,jars/aws-java-sdk-1.11.179.jar

In the shell, here is how I try to load data from the S3 bucket:

val p = spark.read.textFile("s3a://sparkcookbook/person")

And here is the error that results:

java.lang.NoClassDefFoundError: org/apache/hadoop/fs/GlobalStorageStatistics$StorageStatisticsProvider
  at java.lang.Class.forName0(Native Method)
  at java.lang.Class.forName(Class.java:348)

  at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:373)
  at org.apache.hadoop.fs.Path.getFileSystem(Path.java:295)

When I instead try to start the Spark shell as follows:

bin/spark-shell --packages org.apache.hadoop:hadoop-aws:2.8.1

Then I get two errors: one when the interperter starts, and another when I try to load the data. Here is the first:

:: problems summary ::

    unknown resolver null

And here is the second:

Could someone suggest how to get this working? Thanks.

Answer 1

If you are using Apache Spark 2.2.0, then you should use hadoop-aws-2.7.3.jar and aws-java-sdk-1.7.4.jar.

$ spark-shell --jars jars/hadoop-aws-2.7.3.jar,jars/aws-java-sdk-1.7.4.jar

After that, when you will try to load data from S3 bucket in the shell, you will be able to do so.
