Subject Re: Wire compatibility between Hadoop 3.x client and 2.x server
Date Wed, 28 Oct 2020 10:16:33 GMT
Hi  VinayaKumar and Wei-Chiu

I filed jira https://issues.apache.org/jira/browse/HDFS-15660 for details

Hi Wu,Jianliang,
Have you created the Jira for the issue you mentioned due to
getContentSummary?

I might have a fix for this. Of-course it needs to be applied both client
and server side.

Let me know.

-Vinay

Thanks Jialiang for reporting the issue.
That sounds bad and should've not happened. Could you file a HDFS jira
and
fill in more details?

In our case, when nn has upgraded to 3.1.3 and dn’s version was still
2.6,  we found hive to call getContentSummary method , the client and
server was not compatible  because of hadoop3 added new PROVIDED storage
type.
