Hi,
I met with a weird problem when using HBase. There are 3 machines: 1 master and
2 region servers (wlu-rs1/10.27.17.251 and wlu-rs2/10.27.16.11).
But when I use "status 'detailed'" to see region servers' status, it show there
are three server, and one server appears twice (exactly same).

Hi guys,
We're currently using 0.90 from the maven repo, and would
love to upgrade to 0.92, but can only find a recent

Many things going on here.

be cleared until all the regions it contains are flushed.

At the request of many, the call-for-papers deadline for Hadoop Summit has been
extended by two weeks to March 7th.
Also, please note that you only need to submit an abstract at this time. You
will have much more time to create your actual presentations.

One minor clarification:
HBase is primarily built for retrieving a single row at a time based on a
predetermined and known location (the key).
Substitute that with: "HBase is primarily built for retrieving sets of
contiguous sorted rows based on a predetermined and known location (the start

I believe Solr has a bunch of plug-ability to write your own custom ranking
approach. If you think you can't do your desired ranking with Solr, you're
probably wrong and need to ask for help from the Solr community.

Hi
We are using Spring Security and HBase in our product. We are adding ACL
support through Spring and are looking at implementing the ACL store in
HBase. I just wondered if anyone else has done this, and if so, maybe
they could share code/experiences?

Mr Gupta,
Thanks so much for your reply!
In my use cases, retrieving data by keyword is one of them. I think Solr is
a proper choice.
However, Solr does not provide a complex enough support to rank. And,
frequent updating is also not suitable in Solr. So it is difficult to
retrieve data randomly
Bing,
Its a classic battle on whether to use solr or hbase or a combination of
both. both systems are very different but there is some overlap in the
utility. they also differ vastly when it compares to computation power,
storage needs, etc. so in the end, it all boils down to your use case. you

There is no secondary index support in HBase at the moment.
It's on our road map.

Jacques,
Yes. But I still have questions about that.
In my system, when users search with a keyword arbitrarily, the query is
forwarded to Solr. No any updating operations but appending new indexes
exist in Solr managed data.
When I need to retrieve data based on ranking values, HBase is used. A

Maybe this utility in hbase helps do what Jacque sugg
Agreed, you could use Solr on top of HBase though.

It is highly unlikely that you could replace Solr with HBase. They're
really apples and oranges.

HBase doesn't have the concept of a globally unique auto-incrementing "ID"

Thanks for the suggestion. I did use List with size 1000, actually the
performance was not that different from deleting one row at a time.
I investigated HRegion.delete() method, my understanding is that when you call
delete() to delete a row, it's actually going to delete all the column families
Dear all,
I wonder how data in HBase is indexed? Now Solr is used in my system
because data is managed in inverted index. Such an index is suitable to
retrieve unstructured and huge amount of data. How does HBase deal with the
issue? May I replaced Solr with HBase?
Thanks so much!
