Subject [jira] [Updated] (HADOOP-12811) Change kms server port number which conflicts with HMaster port number
Date Wed, 13 Apr 2016 18:27:25 GMT

]

Xiao Chen updated HADOOP-12811:
-------------------------------
    Attachment: HADOOP-12811.01.patch

HDFS-9427 seems to be close to commit. I'm attaching a patch for review. KMS port is changed
from 16000 to 9600. Thanks.

I picked 9600 because it's in the same range as HDFS-9427. I also searched apache github,
9600 seems to not being used by other applications. (except [juddi|https://juddi.apache.org/],
which I feel should be Okay.)

Also searched across projects for 16000, and found impala should update [some files|https://github.com/apache/incubator-impala/search?utf8=%E2%9C%93&q=16000]
due to this change. But that should be implicit by the 'incompatible' flag anyway. :)

> 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.
