alborotogarcia opened a new issue #12087:
URL: https://github.com/apache/druid/issues/12087
Coordinator always restarts when I set minio/hdfs for deep storage
### Affected Version
v0.22.1
### Description
I'm new to druid, I see that in order to persist segments deep storage is
needed.
As the docs say, It is needed to enable the "druid-s3-extensions" or
"druid-hdfs-storage" extensions in the loadlist, so that it get sets from
configmap.
In case of hdfs as deep storage it is also needed the core-site.xml and
hdfs-site.xml but the coordinator pod always gets restarted with no trace.
Please include as much detailed information about the problem as possible.
- Cluster size
6 nodes
- Configurations in use
mostly defaults from helm/druid, everything is fine If I don't set s3/hdfs
for deep storage
```
druid_storage_type: hdfs
druid_storage_storageDirectory: hdfs://hadoop-hdfs-nn.hdfs:8020/druid
# druid_storage_type: s3
# druid_storage_bucket: s3://druid
# druid_s3_endpointUrl: http://myminioinstance.svc.cluster.local:9000
# druid_s3_accessKey: miniokey
# druid_s3_secretKey: miniopass
```
- Steps to reproduce the problem
- The error message or stack traces encountered. Providing more context,
such as nearby log messages or even entire logs, can be helpful.
- Any debugging that you have already done
I set core-site.xml and hdfs-site.xml as a configmap same as my hadoop
deployment
```
apiVersion: v1
kind: ConfigMap
metadata:
name: hadoop
data:
core-site.xml: |
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://hadoop-hdfs-nn.hdfs:8020/</value>
<description>NameNode URI</description>
</property>
</configuration>
hdfs-site.xml: |
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration><property>
<name>dfs.webhdfs.enabled</name>
<value>true</value>
</property><property>
<name>dfs.datanode.use.datanode.hostname</name>
<value>true</value>
</property>
<property>
<name>dfs.client.use.datanode.hostname</name>
<value>true</value>
</property>
<property>
<name>dfs.replication</name>

</property>
<property>

<value>file:///root/hdfs/datanode</value>
<description>DataNode directory</description>
</property>
<property>
<name>dfs.namenode.name.dir</name>
<value>file:///root/hdfs/namenode</value>
<description>NameNode directory for namespace and transaction logs
storage.</description>
</property>
<property>
<name>dfs.namenode.datanode.registration.ip-hostname-check</name>
<value>false</value>
</property>
<!-- Bind to all interfaces -->
<property>
<name>dfs.namenode.rpc-bind-host</name>
<value>0.0.0.0</value>
</property>
<property>
<name>dfs.namenode.servicerpc-bind-host</name>
<value>0.0.0.0</value>
</property>
<!-- /Bind to all interfaces -->
</configuration>
```
So it gets mounted on the conmon subpath
```
volumeMounts:
- name: hadoop-config
mountPath: /opt/druid/conf/druid/cluster/_common/core-site.xml
subPath: core-site.xml
- name: hadoop-config
mountPath: /opt/druid/conf/druid/cluster/_common/hdfs-site.xml
subPath: hdfs-site.xml
volumes:
- name: hadoop-config
configMap:
name: hadoop
```
I tried creating my /druid root folder on hdfs just in case, though no
difference so far..
```
~ k get svc -nhdfs

Here is the coordinator trace..

After a while it gets restarted
