Subject [jira] [Commented] (HDFS-3315) Improve bootstrapStandby error message when other NN has misconfigured http address
Date Tue, 24 Apr 2012 05:08:35 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13260224#comment-13260224
] 

Aaron T. Myers commented on HDFS-3315:
--------------------------------------

Another thing we could do would be to see if the HTTP/S address we determine for the other
NN is the same as the HTTP/S address for _this_ NN. I suspect that would catch the most common
case.

> Currently, if the user forgets to configure the HTTP server address distinctly for each
NN, bootstrapStandby emits and ugly stack trace with little indication as to which config
is the issue. We should catch the exception and display a more actionable error message.
