It is perhaps because there are already other ways to get the relevant information. E.g., I do not have any experience with Ambari, but it must be checking and reporting versions through jmx, etc. In other words, rather than having Hadoop's built-in reporting mechanism actually work and give useful information, we should require a third party tool or make ops teams write their own reporting tools even though it's going to be an absolutely common request/requirement after rolling upgrades become more common place? > Display the server version in dfsadmin -report > -- > > Key: HDFS-402 > URL: https://issues.apache.org/jira/browse/HDFS-402 > Project: Hadoop HDFS > Issue Type: Improvement >Reporter: Jakob Homan >Assignee: Uma Maheswara Rao G >Priority: Minor > Labels: newbie > Attachments: HDFS-402.patch, HDFS-402.patch, HDFS-402.patch, > hdfs-402.txt > > > As part of HADOOP-5094, it was requested to include the server version in the > dfsadmin -report, to avoid the need to screen scrape to get this information: > bq.

My comments were just for the patch :) I'm just thinking if its worth sending that version info (beyond RPC version which we already do) for just this purpose. Second point is that with metrics and such data exposed now, that should be the direction we should be pushing the monitoring at. I doubt if "dfsadmin -report" even stands close to that, though it is nifty as it stands today and shouldn't be removed. Just shouldn't be suggested to be used for monitoring, or checking, over the metrics stuff?

Hey Harsh, This should not be the finalized version of the patch. Did you check
my comments above? Patch is just another way for the Dhruba's suggestion.
Since there was a discussion before this, i just updated as per their
discussion and asked for the remaining clarification on my above comment.
Thanks for your comments.

If we really need to get the version info from NN, then we may need to expose
some api in Filesystem to get into DFSAdmin, else above patch can satisfy the
needs.

Harsh J commented on HDFS-402:
--
-1 on that patch, its not the 'required' fix for this JIRA.
An easy misleader with that would be that the client running report will print
0.23.1 while the real server version may just be 0.23.0. This is not what is
required.
But FWIW, version is present in the web UI and in metrics today. ("name" :
"hadoop:service=NameNode,name=NameNodeInfo" carries a 'Version' param.)
Also, if the client is incompatible, a better message is thrown (in 0.23+)
indicating the protocol version differences (not version string, however).
