Luis Pigueiras created HDFS-17680:
-------------------------------------
Summary: HDFS ui in the datanodes doesn't redirect to https when
dfs.http.policy is HTTPS_ONLY
Key: HDFS-17680
URL: https://issues.apache.org/jira/browse/HDFS-17680
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode, ui
Affects Versions: 3.4.1
Reporter: Luis Pigueiras
_(I'm not sure if I should put it in HDFS or in HADOOP, feel free to move it if
it's not the correct place)_
We have noticed that with having a https_only configuration when accessing the
datanodes from the namenode UI, there is a wrong redirection when clicking on
the link of the datanodes.
If you visit in the hdfs UI of a namenode:
https://<node>:50070/ -> datanodes -> click on the datanode you get redirected
from https://<node>:9865 to http://<node>:9865. The 302 should redirect to
https and not to http. If you do a curl to the link that is exposed on the
website, you get the redirected to the wrong place.
{code}
curl -k https://testing2475891.example.org:9865 -vvv
...
< HTTP/1.1 302 Found
< Location: http://testing2475891.example.org:9865/index.html
{code}
This issue is present in our 3.3.6 but it's also present in 3.4.1 because I
managed to reproduce it with the following steps:
- Download latest version (binary from:
[https://hadoop.apache.org/releases.html] -> 3.4.1)
- Uncompress the binaries:
{code:java}
tar -xvf hadoop-3.4.1.tar.gz
cd hadoop-3.4.1
{code}
- Generate dummy certs for TLS and move them to {{etc/hadoop}}
{code:java}
keytool -genkeypair -alias hadoop -keyalg RSA -keystore hadoop.keystore
-storepass changeit -validity 365
keytool -export -alias hadoop -keystore hadoop.keystore -file hadoop.cer
-storepass changeit
keytool -import -alias hadoop -file hadoop.cer -keystore hadoop.truststore
-storepass changeit -noprompt
cp hadoop.* etc/hadoop
{code}
- Add this to {{etc/hadoop/hadoop-env.sh}}
{code:java}
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk
export HDFS_NAMENODE_USER=root
export HDFS_DATANODE_USER=root
export HDFS_SECONDARYNAMENODE_USER=root
{code}
- Create a etc/hadoop/ssl-server.xml with:
{code:java}
<configuration>
<property>
<name>ssl.server.truststore.location</name>
<value>/root/hadoop/hadoop-3.4.1/etc/hadoop/hadoop.truststore</value>
<description>Truststore to be used by NN and DN. Must be specified.
</description>
</property>
<property>
<name>ssl.server.truststore.password</name>

<description>Optional. Default value is "".
</description>
</property>

</description>
</property>
<property>
<name>ssl.server.truststore.reload.interval</name>
<value>10000</value>
<description>Truststore reload check interval, in milliseconds.
Default value is 10000 (10 seconds).

</property>
<property>

SSL_RSA_EXPORT_WITH_RC4_40_MD5,SSL_RSA_EXPORT_WITH_DES40_CBC_SHA,

- Now you can initialize:
{code:java}
bin/hdfs namenode -format
sbin/start-dfs.sh
{code}
- If you visit https://<node>:50070/ -> datanodes -> click on the datanode you
get redirected from https://<node>:9865 to http://<node>:9865
{code}
curl -k https://testing2475891.example.org:9865 -vvv
