Xiao Chen commented on HADOOP-12811:
------------------------------------
Thanks Yufeng for creating this. I've linked HDFS-9427 which will change HDFS
default ports.
I'd like to work on this, but I'm thinking to wait for HDFS-9427 to be agreed
and committed to avoid conflicts. Then I plan to change the default kms port to
be in the same range (e,g, 9170 if HDFS-9427 goes with 9070).
The only problem I can think of this change is backwards compatibility. Added a
label to this jira.
> Change kms server port number which conflicts with HMaster port number

> Key: HADOOP-12811
> URL: https://issues.apache.org/jira/browse/HADOOP-12811
> Project: Hadoop Common
> Issue Type: Improvement
> Components: kms
> Affects Versions: 2.6.1, 2.7.0, 2.7.1, 2.7.2, 2.6.2, 2.6.3
> Reporter: Yufeng Jiang
> Labels: incompatible, patch
>
> The HBase's HMaster port number conflicts with Hadoop kms port number. Both
> uses 16000.
> There might be use cases user need kms and HBase present on the same cluster.
> The HBase is able to encrypt its HFiles but user might need KMS to encrypt
> other HDFS directories.
> Users would have to manually override the default port of either application
> on their cluster. It would be nice to have different default ports so kms and
> HBase could naturally coexist.
