[Marino]

Hi

I was installing hounder. After ./start-all.sh and then ./
status.sh I got:
crawler: running
indexer: running
searcher: not running <-----------------
cache-server: running
clustering-web: running


http:localhost:47050/index.do givs me in the current node list:

localhost:47041:/var/local/hounder/searcher searcher UNREACHABLE

with:

I got the hounder up and running after 2 fixes, here they come.
I'm using Debian with 2 interfaces on the network (10.1.x.x and
157.157.xxx.xxx)

after clean install:

/var/local/hounder/searcher/start.sh
The searcher is not running
Starting the searcher...

/var/local/hounder/searcher# ./status.sh
The searcher is not running

/var/local/hounder/searcher/logs# more searcher.err
Exception in thread "main" java.lang.NoClassDefFoundError: 157/157/xxx/
xxx
Caused by: java.lang.ClassNotFoundException: 157.157.xxx.xxx

at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:

Could not find the main class: 157.157.xxx.xxx. Program will exit.


==> FIX: I removed the 157.157.xxx.xxx from the machine, having
10.1.x.x left.

reboot

/var/local/hounder/searcher# ./start.sh
The searcher is not running
Starting the searcher...

/var/local/hounder/searcher# ./status.sh
The searcher is running


==> this left me with searcher status BAD

/var/local/hounder/searcher/logs# more hounder.log

...

apt-get install rsync

reboot

did a clean install

I had to wait a bit, first the searcher status was still BAD with No
indexId
but afer a while the it changed to GOOD,

PROBLEM SOLVED ;)
