Getting started with Hypertable!

[erik]

Hi!
I'm just getting started with Hypertable and trying it out, but have
encountered some problems:
1. When editing the fstab file I don't really know where to put the
extra line. It look like this now:

/dev/VolGroup00/LogVol00 / ext3
defaults,user_xattr 1 1
LABEL=/boot /boot ext3
defaults 1 2
tmpfs /dev/shm tmpfs
defaults 0 0
devpts /dev/pts devpts
gid=5,mode=620 0 0
sysfs /sys sysfs
defaults 0 0
proc /proc proc
defaults 0 0
/dev/VolGroup00/LogVol01 swap swap
defaults 0 0

just put the user_xattr at the top

2. When I start the master I get:
$ ./start-master.sh hadoop
./start-master.sh: line 106: /home/erik/hypertable/hypertable/bin/
serverup: No such file or directory
./start-master.sh: line 121: /home/erik/hypertable/hypertable/bin/
serverup: No such file or directory
DfsBroker (hadoop) hasn't come up yet, trying again in 5 seconds ...
./start-master.sh: line 126: /home/erik/hypertable/hypertable/bin/
serverup: No such file or directory
Num CPUs=2
HdfsBroker.Port=38030
HdfsBroker.Reactors=2
HdfsBroker.Workers=20
HdfsBroker.Server.fs.default.name=hdfs://localhost:9000
Problem statring DfsBroker (hadoop)

Not sure if these 2 issues are related, but but.


I have a hadoop node up and running and i looks like this:

Hi Eric,

Your fstab file looks correct.  You also need to run the following command:

mount -o remount /

From the error message " ./start-master.sh: line 106: /home/erik/hypertable/hypertable/bin/serverup: No such file or directory"  it looks like the software has not been installed properly.  Try walking through the README file step-by-step and get the regression tests to pass.  After they are passing, the software should be installed properly and things should be working properly.  If you still have problems after that, let me know.

Hey Doug!
And thanks for the answer, I tried to do everything according to the instructions, but
at first it didn't work and I got the same error message as before, but then I found a
.rpm of the liblog4cpp and installed it, then things started to work.

I tried the example_hql and that worked fine, but then I was looking to write some
small test program in C++, but I couldn't seem to locate the api and not really sure
how to set it up.

Hi Eric,

Look in the examples/apache_log directory.  It contains a working example with a README file that explains how to get it compiling in your environment.

Thanks Doug!
I found the library and changed the variables in the Makefile into:

BOOST_INCLUDE_DIR=/usr/local/include/boost-1_35
BOOST_THREAD_LIB=boost_thread-mt
HYPERTABLE_INSTALL_DIR=/home/erik/hypertable/hypertable

Not sure about the second one, couldn't find it.

Then I used the make file.

But when typing:
[root@erik0 apache_log]#  ./../../bin/hypertable --batch < WebServerLog-create-table.hql

I get:
-bash: WebServerLog-create-table.hql: No such file or directory
