mrjob返回非零退出状态256

我是地图还原的新手,我正在尝试使用 mrjob python包。但是,我遇到了以下错误:

ERROR:mrjob.launch:Step 1 of 1 failed: Command '['/usr/bin/hadoop', 'jar', '/usr/lib/hadoop-mapreduce/hadoop-streaming.jar', '-files',

我试过在本地用 python ./word_count.py input/test-1.warc > output

我在用

1. python 2.7.14
2. Hadoop 2.8.3-amzn-1
3. pip 18.0
4. mrjob 0.6.4

这是我运行mapreduce作业时的命令。我是从 cc-mrjob run_hadoop.sh 我用 chmod +x run_hadoop.sh

#!/bin/sh

JOB="$1"
INPUT="$2"
OUTPUT="$3"

sudo chmod +x $JOB.py

if [ -z "$JOB" ] || [ -z "$INPUT" ] || [ -z "$OUTPUT" ]; then
    echo "Usage: $0 <job> <input> <outputdir>"
    echo "  Run a CommonCrawl mrjob on Hadoop"
    echo
    echo "Arguments:"
    echo "  <job>     CCJob implementation"
    echo "  <input>   input path"
    echo "  <output>  output path (must not exist)"
    echo
    echo "Example:"
    echo "  $0 word_count input/test-1.warc  hdfs:///.../output/"
    echo
    echo "Note: don't forget to adapt the number of maps/reduces and the memory requirements"
    exit 1

我和你一起跑 ./run_hadoop.sh word_count test-1.warc output

哪里

• word_count 作业(文件)名为 word_count.py )
• test-1.warc 输入(位于 hdfs:///user/hadoop/test-1.warc )
• 和 output hdfs:///user/hadoop/output )我还确保我总是对不同的作业使用不同的输出,以防止重复的文件夹)

*更新*

我查看了系统日志的界面。有一个错误

org.apache.hadoop.mapreduce.v2.app.rm.RMContainerAllocator: Could not deallocate container for task attemptId attempt_1536113332062_0001_r_000003_0

这和我犯的错误有关吗?

我在一次地图尝试中也得到了这个

/bin/sh: run_prestart: line 1: syntax error: unexpected end of file

和

No module named boto3
