Subject [jira] [Updated] (HBASE-5735) Clearer warning message when connecting a non-secure HBase client to a secure HBase server
Date Fri, 06 Apr 2012 03:31:20 GMT

     [ https://issues.apache.org/jira/browse/HBASE-5735?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Shaneal Manek updated HBASE-5735:
---------------------------------

    Status: Patch Available  (was: Open)

Give a more specific error message if a current, but insecure, client is attempting to connect
to a secure HBase server.

Several users have reported being confused by the more generic error message (thinking they
were using old client JARs, etc).

> When a connection from a non secure-rpc-engine
> client is attempted the warning message you get is related to version
> mismatch:
> Mar 28, 3:27:13 PM WARN org.apache.hadoop.ipc.SecureServer Incorrect
> header or version mismatch from 172.29.82.121:43849 got version 3
> expected version 4
> While this is true, it isn't as useful as it could be. A more specific error message
warning end users that they're connecting with a non-secure client may be more useful.
