Hello Arron,
Hahaha, I just found the problem. It was a cloned virtual host. I
went in and changed the hostname to the new hostname, but I did NOT
change the entry in the /etc/hosts file. I just noticed this, fixed it,
and then tried the create table command without any problems.
Now that we know why it was occurring, hunting down the problem and
fixing it in the code, or giving some different kind of error shouldn't
be too hard to do. Problem is fixed for me now though.
I do have a few question if you don't mind... I am still trying to
wrap my head around how this works. In my current implementation for a
logging system I create new indexes for each hour because I have a
massive amount of data coming in. I take in live log data from syslog
and parse/store it in hourly lucene indexes along with a facet index. I
want to turn this into a distributed redundant system and blur appears
to be the way to go. I tried elasticsearch but it is just too slow
compared to my current implementation. Given I take in gigs of raw log
data an hour, I need something that is robust and able to keep up with
in flow of data.
Does blur handle facet indexing as well? I looked at the javadocs
and did notice some facet objects, but didn't see any examples on how to
access that information.
When taking in lots of data constantly, how is it recommended that
it be stored? I mentioned above that I create a new index for each hour
to keep data separated and quicker to search. If I want to look up a
specific time frame, I only have to load the directories timestamped
with the hours I want to look at. So instead of having to look at a huge
index of like a years worth of data, i'm looking at a much smaller data
set which results in faster query response times. Should a new table be
created for each hour of data? When I typed in the create command into
the shell, it takes about 6 seconds to create a table. If I have to
create a table for each application each hour, this could create a lot
of lag. Perhaps this is just in my test environment though. Any thoughts
on this? I also didn't see any examples of how to create tables via code.
From what I understand when developing with blur, the code acts as
a client to connect to a controller server. If you have more than one
controller, do you have to specify them all? Does the client have to
connect to all of them, or does it use the list and try to connect to
each host in the list until it's successful?
The controller server acts like the query handler right? Does the
controller reach out to the shards, get the data, run the query again
it, and return the results to the client, or does each shard process the
query and return the results from the dataset it has, then the
controller aggregates the results and responds to the client? Just
trying to understand where the main processing of the query is done.
Do shards contain the index data while the location (hdfs) contains
the documents (what lucene referred to them as)? I read that the shard
contains the index while the fs contains the data... I just wasn't quiet
sure what the data was, because when I work with lucene, the index
directory contains the data as a document.
Thanks,

Colton,
First off welcome, hope we can help you get started or at least past this
issue. The the binary artifact of Blur bundles hadoop to try and get
people up and running as quickly as possible. Obviously it has not done
it's job in this case. ;-)
Could you please post the shard and controller logs? Also are you running
hadoop 1.x (CDH3) or hadoop 2.x (CHD4)? Or are you just trying to get it
to work with the internal embedded version of hadoop? Or all of the
above? Also have you set anything in the blur-env.sh file or is it the
vanilla version? Just trying to cover all the bases here. I just walked
through the getting started guide on centos 6.x and last night I walked
through it on ubuntu 12.03? (I think) the LTS version with success.
I have found 2 issues with it, but neither seem related to the error you
are getting.
- One is an error with the default MaxDirectMemorySize setting in the
blur-env.sh, if left at the default it will throw an OOM exception when it
gets full (which shouldn't happen), but set larger it works as expected.
- The other is related to some status jsp pages in the daemon processes.
Let me know.
Thanks,
Aaron

Hello All,
I am trying to get blur operating on a virtual environment using
gentoo as a base. I have compiled the latest version of blur as well as
tried the 0.2.0 tagged version. Each time I go to try and create a table, I
get an IOException saying the table already exists. Here is a basic example
of what I have done...
hadoop@blur ~ $ tar xfz apache-blur-0.3.0-incubating-**SNAPSHOT-bin.tar.gz
hadoop@blur ~ $ mv apache-blur-0.3.0-incubating-**SNAPSHOT-bin blur
hadoop@blur ~ $ cd blur
hadoop@blur ~/blur $ bin/start-all.sh
localhost: ZooKeeper starting as process 9536.
localhost: Shard [0] starting as process 9598.
localhost: Controller [0] starting as process 9660.
hadoop@blur ~/blur $ bin/blur shell
blur (default)> create -t testtable -c 11 -l file:///tmp/testtable
java.io.IOException: Table [testtable] already exists.
blur (default)> enable testtable
java.io.IOException: Table [testtable] already enabled.
blur (default)> disable testtable
java.io.IOException: Table [testtable] already disabled.
blur (default)> remove testtable
blur (default)>
As one can see from the above commands, this is a fresh attempt at
starting blur as the instructions on the site provide. I have tried the
following versions of jdk with the same problem...
[1] icedtea-bin-6
[2] icedtea-bin-7
[3] oracle-jdk-bin-1.7
[4] sun-jdk-1.6
Between attempts I made sure to delete /tmp/zk_data to avoid any
possible problems it was causing. Each time I would experience the same
problem when trying to create a table as a test. I tried this on a ubuntu
virtualbox and it worked. I don't understand why there would be a
difference between the two considering I tried the same versions of java.
The ubuntu system was using openjdk 7 which is what gentoo calls
icedtea-bin-7.
When using debug and timed responses, here is what gets outputted when
typing the same commands...
blur (default)> debug
debugging is now on
blur (default)> timed
timing of commands is now on

I emailed Aaron directly who suggested I make sure I clear the

Any help in resolving this would be greatly appreciated.
