Hey Sambit,
Your best bet is to use an append-supportive release, such as Apache Hadoop
0.20.205 (or Apache Hadoop 1.0.0 which is a revision on top of that, out soon).
Do read http://hbase.apache.org/book.html#hadoop for explicit guidelines on
selecting the right Hadoop version for HBase.
With
Hi,
I am going to install HBase on my beowulf cluster which has hadoop
0.20.203.rc1 for test purposes.
Which is the stable version of HBase that works along with
hadoop-0.20.203.rc1? Any experiences so far?
Thanks
Sambit
Hi,
No need for the pardon:)
Ok. I'll investigate getting the noexec taken off, I already have but
everyone is on holidays. Thanks for all of your help.
Cheers

Pardon me. Thats I thought you just wanted to change the hbase ho
Hi,
The hbase.rootdir was already using a folder under /var and since yesterday
I changed the HBASE_PID_DIR to use /var/hadoop/pids.
The error hasn't changed at all.

Some time ago, we had a situation where our REST server was slammed
with queries that did not find any matches for rows in Hbase. When
that happened we sustained 50k rpc/sec to META region server as
reported by the master web page. After digging deeper we found that
reach request with 'wrong' url
That's my github but I don't regularly push there -- so it's a bit out of
date. Working from the apache svn is probably the best bet

Thanks Jon,

Hello - I am trying to figure out the best way to architect access to an
HBase cluster from a multi-user system that has potentially thousands of
processes all potentially reading and writing data from/to HBase. The
multi-user system is a collection of processes written in C or C++
(essentially a c

Have a look into the JRuby source of that script. It is trivial to patch it so
that it does what you want.

patch_meta.rb has some problems. I ran it, and it would create region
start/end combos, there were incorrect in terms of order, for example
"dab - cab", which is a region that is not right, because first key is
greater than end key. I guess what I really need is a very simple

Simple script based on the check_meta.rb to patch holes.
