[~yuan_zac] Thanks! I've reproduced your issue and double-checked the patch. It 
solves the HDFS connection issue caused by wrong HADOOP_COMMON_HOME value which 
causes invalid classpath and the TF job hung there.

Both set it empty or correct works per my testing.
{code:java}
fw.append("export HADOOP_COMMON_HOME=\n");{code}
[~sunilg] or [~leftnoteasy] Could you help merge the patch? Thanks!

In my case, launch_container.sh specified HADOOP_COMMON_HOME like this:

export HADOOP_COMMON_HOME=${HADOOP_COMMON_HOME:-"/home/hadoop/yarn-submarine"}
 export HADOOP_HDFS_HOME=${HADOOP_HDFS_HOME:-"/home/hadoop/yarn-submarine"}
 export HADOOP_CONF_DIR=${HADOOP_CONF_DIR:-"/home/hadoop/yarn-submarine/conf"}
 export HADOOP_YARN_HOME=${HADOOP_YARN_HOME:-"/home/hadoop/yarn-submarine"}
 export HADOOP_HOME=${HADOOP_HOME:-"/home/hadoop/yarn-submarine"}

 

I think, the HADOOP_COMMON_HOME in launch_container.sh would take effect in 
run-PRIMARY_WORKER.sh. ~

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

{code}
But, if a wrong  HADOOP_COMMON_HOME is specified 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
