我收到一个错误
docker: Error response from daemon: rpc error: code = 2 desc = "oci runtime error: exec format error".
我的 entrypoint.sh 文件看起来像
/usr/bin/docker-quickstart
service hadoop-hdfs-namenode restart
hdfs dfs -mkdir -p input
hdfs dfs -put /twitter.avro /input/twitter.avro
spark-submit --class com.abhi.HelloWorld --master local[1] SparkIntegrationTestsAssembly.jar /input/twitter.avro /output
根据 Cloudera's documentation 你应该从 --hostname 和 --priviliged
开始
来自文档
docker run --hostname=quickstart.cloudera --privileged=true -t -i [OPTIONS] [IMAGE] /usr/bin/docker-quickstart
所需标志和其他选项的说明如下table:
--hostname=quickstart.cloudera Required: pseudo-distributed configuration assumes this hostname
--privileged=true Required: for HBase, MySQL-backed Hive metastore, Hue, Oozie, Sentry, and Cloudera Manager, and possibly others
-t Required: once services are started, a Bash shell takes over and will die without this
-i Required: if you want to use the terminal, either immediately or attach later
-p 8888 Recommended: maps the Hue port in the guest to another port on the host
-p [PORT] Optional: map any other ports (e.g. 7180 for Cloudera Manager, 80 for a guided tutorial)
-d Optional: runs the container in the background
您 post 完成 entrypoint.sh 了吗？
内核试图通过查看可执行文件的前几个字节来识别文件类型。对于脚本，您需要添加所谓的 shebang 行。您可能需要在 entrypoint.sh 的最顶部添加一个 shebang 行，例如：
#!/bin/sh
/usr/bin/docker-quickstart
service hadoop-hdfs-namenode restart
hdfs dfs -mkdir -p input
hdfs dfs -put /twitter.avro /input/twitter.avro
spark-submit --class com.abhi.HelloWorld --master local[1] SparkIntegrationTestsAssembly.jar /input/twitter.avro /output
Error response from daemon: rpc error: code = 2 desc = “oci runtime error: exec format error”
就我而言，我在尝试在 32 位 ArchLinux（raspberry pi 2）上安装 docker 时遇到此错误。相反，我使用 HyperioOS and it went alot smoother and was so much faster to install. But in the end, most docker images are not compatible with 32 bit architectures and they outline this 作为出现此错误的可能原因。
Here we run Docker on a Raspberry Pi. So the CPU architecture here is ARM rather than x86/x64 by Intel or AMD. Thus, Docker-based apps you use have to be packaged specifically for ARM architecture! Docker-based apps packaged for x86/x64 will not work and will result in an error
