Ewan Higgs created HDFS-11245:
---------------------------------
Summary: HDFS ignores HADOOP_CONF_DIR
Key: HDFS-11245
URL: https://issues.apache.org/jira/browse/HDFS-11245
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs
Affects Versions: 3.0.0-beta1
Environment: Linux
Reporter: Ewan Higgs
It seems that HDFS on trunk is ignoring {{HADOOP_CONF_DIR}}. On {{branch-2}} I
could export {{HADOOP_CONF_DIR}} and use that to store my {{hdfs-site.xml}} and
{{log4j.properties}}. Also, even if hdfs can find the {{log4j.properties}}, it
doesn't seem interested in opening and loading it.
On Ubuntu 16.10:
{code}
$ source env.sh
$ cat env.sh
#!/bin/bash
export JAVA_HOME=/usr/lib/jvm/java-8-oracle
export
HADOOP_HOME="$HOME"/src/hadoop/hadoop-dist/target/hadoop-3.0.0-alpha2-SNAPSHOT
export HADOOP_LOG_DIR=""$(pwd)/log"
PATH="$HADOOP_HOME"/bin:$PATH
export HADOOP_CLASSPATH=$(hadoop
classpath):"$HADOOP_HOME"/share/hadoop/tools/lib/*
export HADOOP_USER_CLASSPATH_FIRST=true
{code}
Then I set the HADOOP_CONF_DIR:
{code}
$ export HADOOP_CONF_DIR="$(pwd)/conf/nn"
$ ls $HADOOP_CONF_DIR
hadoop-env.sh hdfs-site.xml log4j.properties
{code}
Now, we try to run a namenode:
{code}
$ hdfs namenode
2016-12-14 14:04:51,193 ERROR [main] namenode.NameNode: Failed to start
namenode.
java.lang.IllegalArgumentException: Invalid URI for NameNode address (check
fs.defaultFS): file:/// has no authority.

{code}
This is weird. We have the {{fs.defaultFS}} set:
{code}
$ grep -n2 fs.defaultFS $HADOOP_CONF_DIR/hdfs-site.xml
3-<configuration>
4- <property>
5: <name>fs.defaultFS</name>
6- <value>hdfs://localhost:60010</value>
7- </property>
{code}
So if isn't finding this config. Where is is looking and finding {{file:///}}?
{code}
$ strace -f -eopen,stat hdfs namenode 2>&1 | grep hdfs-site.xml

So it's ignoring {{HADOOP_CONF_DIR}}. We can work around it using {{-conf

Great! However, it's not finding my log4j.properties for some reason. This is
annoying because hdfs isn't printing anything or logging anywhere. Where is it
looking?
{code}
$ strace -f hdfs namenode -conf $(pwd)/conf/nn/hdfs-site.xml 2>&1 | grep
log4j.properties
stat("/home/ehigg90120/src/hadoop-run/tutorial/conf/nn/log4j.properties",
{st_mode=S_IFREG|0644, st_size=13641, ...}) = 0
{code}
It found it, but it only statted it. It never opened it! So it seems there's at
least one bug here where {{log4j.properties}} is being ignored. But shouldn't
{{HADOOP_OPTS}} be set and configuring it to print to the console and to my log
dir?
{code}
$ hdfs --debug namenode -conf $(pwd)/conf/nn/hdfs-site.xml 2>&1 | grep

{code}
So it seems it is being configured and passed to the namenode. It's just not
obeying it as far as I can see.
So maybe there are two possibly related bugs:
1. {{HADOOP_CONF_DIR}} is ignored
2. The logger is not using {{log4j.properties}} or the command line. I would
expect it to use the {{log4j.properties}} in the {{HADOOP_CONF_DIR}}.
I feel like I must be misunderstanding something since this seems like a pretty
big issue but I didn't find any open tickets about it or any tickets describing
a new way of configuring clusters.
