Subject [jira] [Comment Edited] (HDFS-12466) Ozone: KSM: Add log message to print host and port used by KSM during startup
Date Tue, 19 Sep 2017 02:08:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16170997#comment-16170997

--------------------------------------------------------------

[~nandakumar131]  What we need to do is warn any client attempting to connect to KSM but the
address matches the default 0.0.0.0 address. With a single node deployment, the code will
work since clients will be able to find the KSM even if this address is not explicitly configured.


However, if the data node or the client is on a different machine then it stops working. So
the same config file that works on a single node deployment will not work on when we have
more than one machine. I think we should log that make it very easy for a user to find what
the issue is. 

[~cheersyang], [~xyao], [~msingh] comments?



was (Author: anu):
[~nandakumar131] Yes, please let us warn if the KSM is not setup and we are going to use the
default 0.0.0.0 address.
