Hi [~tangzhankun],
yeah, I specified "DOCKER_HADOOP_HDFS_HOME" to /hadoop-3.1.0 which is the
hadoop home directory in docker image.
In docker, DOCKER_HADOOP_HDFS_HOME takes effect, but it is not enough.
I think you can test it even without docker env.
when you just specify HADOOP_HDFS_HOME, it works well as follows:
{code:java}
hadoop@hostname:~/zq/submarine-lib/hadoop-3.2.0-SNAPSHOT$ export
HADOOP_HDFS_HOME=/home/hadoop/zq/submarine-lib/hadoop-3.2.0-SNAPSHOT
hadoop@hostname:~/zq/submarine-lib/hadoop-3.2.0-SNAPSHOT$ echo $HADOOP_HDFS_HOME
/home/hadoop/zq/submarine-lib/hadoop-3.2.0-SNAPSHOT
hadoop@hostname:~/zq/submarine-lib/hadoop-3.2.0-SNAPSHOT$ ./bin/hadoop
classpath --glob
HADOOP_SUBCMD_SUPPORTDAEMONIZATION: false
HADOOP_SUBCMD_SECURESERVICE: false
HADOOP_DAEMON_MODE: default
/home/hadoop/yarn-submarine/etc/hadoop:/home/hadoop/yarn-submarine/share/hadoop/common/lib/jaxb-api-2.2.11.jar:/home/hadoop/yarn-submarine/share/hadoop/common/lib/commons-lang3-3.7.jar:/home/hadoop/yarn-submarine/share/hadoop/common/lib/gson-2.2.4.jar:/home/hadoop/yarn-submarine/share/hadoop/common/lib/paranamer-2.3.jar:
{code}
But, if you specify a wrong HADOOP_COMMON_HOME with a correct
HADOOP_HDFS_HOME, it will fail.
{code:java}
hadoop@hostname:~/zq/submarine-lib/hadoop-3.2.0-SNAPSHOT$ export
HADOOP_COMMON_HOME=/home/hadoop
hadoop@hostname:~/zq/submarine-lib/hadoop-3.2.0-SNAPSHOT$ ./bin/hadoop
classpath --glob
