以下代码适用于OSX

var hadoopInputFile  = org.apache.parquet.hadoop.util.HadoopInputFile.fromPath(parquetPath, new Configuration())

但在Linux上却不是这样

failure to login: javax.security.auth.login.LoginException: java.lang.NullPointerException: invalid null input: name
    at jdk.security.auth/com.sun.security.auth.UnixPrincipal.<init>(UnixPrincipal.java:67)

我发现new com.sun.security.auth.module.UnixSystem().getUsername()返回null,但它不应该返回
有什么想法可以修复或解决吗?
不间断电源
因为这是在码头集装箱内发生的
停靠文件:

FROM maven:3.8.5-openjdk-17 AS tests
ENV WORKDIR="/application"
WORKDIR ${WORKDIR}
COPY . $WORKDIR/

运行命令:

docker run
        --user 0:1001
        --volume $(command -v docker):/usr/bin/docker
        --volume /var/run/docker.sock:/var/run/docker.sock
        --volume $(pwd):/path/to/project/application
        app_tag bash -c
        "umask 002;
        mvn --settings ./.m2-settings.xml package"

UPD 2
我发现id可以得到uid=1001 gid=1001 groups=1001
以及whoami-whoami: cannot find name for user ID 1001
目前的解决方法是添加到Dockerfile

RUN groupadd -g 1001 sysadmin
RUN useradd appadmin -u 1001 -g 1001 -m -s /bin/bash
v2g6jxz6

v2g6jxz61#

添加到Dockerfile可解决此问题

RUN groupadd -g 1001 sysadmin
RUN useradd appadmin -u 1001 -g 1001 -m -s /bin/bash
