Subject [jira] [Commented] (HBASE-12867) Shell does not support custom replication endpoint specification
Date Thu, 29 Jan 2015 00:11:36 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14296114#comment-14296114
] 

Kevin Risden commented on HBASE-12867:
--------------------------------------

I'll create a follow up JIRA for adding listPeerConfigs and getPeerConfig to the HBase shell.

In the patch why did you have a test that is commented out?
{code}+    # assert_raise fails on native exceptions - https://jira.codehaus.org/browse/JRUBY-5279{code}
{quote}

I wanted to test that when adding a peer with the same id that an exception is thrown up to
the shell. The exception is actually a java.lang.IllegalArgumentException but I can't catch
it with assert_raise. JRUBY-5279 identifies the issue and it looks like it is fixed in JRuby
1.7 but HBase is using JRuby 1.6.8. I can remove the test if that helps.

One last thing is that, regular commands like create table, etc define constants used in hbase-shell/src/main/ruby/hbase.rb.
so that the user does not have to do :CONSTANT, and instead can do CONSTANT. We can do the
same thing for consistency with the other commands.

Ah that makes sense. I was trying to find how the other commands didn't need to use colons.
I'll make this change.

[~risdenk] made the following observations and suggestions regarding custom replication endpoints
that I think are a reasonable blueprint for improvement:
> {quote}
> I was trying out the pluggable replication endpoint feature and found the following:
> - you must use the ReplicationAdmin to add the new ReplicationEndpoint
> - hbase shell add_peer command doesn't support specifying a custom class
> - hbase shell add_peer relies on the newly deprecated ReplicationAdmin addPeer methods
> - ReplicationAdmin addPeer tableCfs is now a Map<TableName, ? extends Collection<String>>
instead of a string
> {quote}
> We should fix the add_peer command in the shell at least.
