Attila Doroszlai updated HDDS-9512:
-----------------------------------
Affects Version/s: 1.4.0
> Ozone Datanode client port conflicts with HDFS Datanode web port
> ----------------------------------------------------------------
>
> Key: HDDS-9512
> URL: https://issues.apache.org/jira/browse/HDDS-9512
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Datanode
> Affects Versions: 1.4.0
> Reporter: WangYuanben
> Assignee: Attila Doroszlai
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.4.0
>
>
> Now in master branch, we have the config like below:
> {code:java}
> <property>
> <name>hdds.datanode.client.port</name>
> <value>9864</value>
> <tag>OZONE, HDDS, MANAGEMENT</tag>
> <description>
> The port number of the Ozone Datanode client service.
> </description>
> </property> {code}
> while HDFS has the config like this:
> {code:java}
> <property>
> <name>dfs.datanode.http.address</name>
> <value>0.0.0.0:9864</value>
> <description>
> The datanode http server address and port.
> </description>
> </property> {code}
> Obviously they share the same port 9864. When starting HddsDatanodeService in
> the node where datanode of HDFS is running, we get the error:
> {code:java}
> Caused by: java.net.BindException: Problem binding to [0.0.0.0:9864]

> This affects the compatibility of Ozone with HDFS. Therefore, maybe we should
> change this port.
