cannot connect with hbase client
I'm running a pseudo-distributed (for the moment) Hadoop server with
HBase on the same server running with 1 master and 1 region. HBase is
successfully talking to HDFS, has created the hbase directory, etc. In
addition, the master/region server are talking just fine. When I try
to connect with the HBase client, I see the following client-side
error:

I'm using Hadoop 0.19.1 with HBase 0.19.0. It was hard to debug to see
why it is sending the subinterface name instead of the interface name
(HRegionInterface), so I can't tell if it is a bug on my end, HBase's
end or something in between. Any help would be appreciated!
Re: cannot connect with hbase client
Posted by Cris Daniluk <cr...@gmail.com>.
I added this to the hbase-site.xml:
<property>
<name>hbase.regionserver.class</name>
<value>org.apache.hadoop.hbase.ipc.TransactionalRegionInterface</value>
</property>
Deleted the hbase folder in hdfs and restarted HBase, but received the
same error. Now, I'm getting it on server startup as well, not just
when the client connects.

Re: cannot connect with hbase client
Posted by Clint Morgan <cl...@troove.net>.
When starting up hbase, you need to tell it to spin up transactional region
servers (impl, not just ipc interface)
from hbase.client.transactional package.html javadoc:
<p> To enable transactions, modify hbase-site.xml to turn on the
TransactionalRegionServer. This is done by setting
<i>hbase.regionserver.class</i> to
<i>org.apache.hadoop.hbase.ipc.TransactionalRegionInterface</i> and
<i>hbase.regionserver.impl </i> to
<i>org.apache.hadoop.hbase.regionserver.transactional.TransactionalRegionServer</i>
BTW, Ive got some fixes for the transactional stuff (possible memory leak,
bug when splitting) that I'll have a patch for this week.

Re: cannot connect with hbase client
Posted by Cris Daniluk <cr...@gmail.com>.
Removed TransactionalRegionInterface from hbase-site.xml and
restarted. I can start up without errors, connect to the web
interfaces of the region and master servers, and connect via the hbase
client.
I just can't connect when I specify TransactionalRegionInterface. The
Jackrabbit client is requesting it in its startup:
config.set("hbase.regionserver.class",
"org.apache.hadoop.hbase.ipc.TransactionalRegionInterface");
config.set("hbase.regionserver.impl",
"org.apache.hadoop.hbase.regionserver.transactional.TransactionalRegionServer");
I'm guessing I missed something in getting the server to use
TransactionalRegionInterface, but not sure what?

Re: cannot connect with hbase client
Posted by stack <st...@duboce.net>.
Its odd in that we're picking up the transactional hbase's ipc rather than
'standard' hbase.
Can you try first outside of jackrabbit? What happens if you run the hbase
shell? Does it connect OK?

Re: cannot connect with hbase client
Posted by Cris Daniluk <cr...@gmail.com>.
I haven't configured anything on the server side whatsoever.. just
hbase.root and master. Is it possible I'm using it on the client-side,
but not the server-side? I found no docs on how to set it on the
server side, and my client is the jackrabbit sandbox driver. It is a
journaled implementation, so I assume by extension it is using the
transactional client.

You are running the transactional hbase subclass intentionally?
If so, could it be that you are not using the transactional client to match?
