Description
A NPE was thrown when I tried to view the simple history for the file system connector. This happened after I tried to delete the connector itself and its belonging jobs.
Apparently I managed to delete the jobs since they went away from the job list, but their status were still in the "cleaning up" state. Entries like this were shown in manifoldcf.log:
WARN 2012-08-10 14:25:10,421 (Worker thread '4') - Pre-ingest service interruption reported for job 1335434066944 connection 'web_crawler': Http response temporary error on 'http://www.apollon.uio.no/vis/art/1998/3/intervju': 503
The Agent process was running as it should.
These problems started to occur after I upgraded from version 0.6 to 1.0 RC0.
I executed the following prior to my upgrade:
crawler.UnRegisterAll
agents.UnRegisterAllOutputs
agents.UnRegisterAll
agents.Uninstall (slette alle tabeller i databasen)
core.LockClean
The configuration was exported and imported back to MCF after the upgrade.
Environment:
- PostgreSQL 9.1.4
- Resin 4.0.27
- solr-test02 mcf-1 $ uname -a
Linux solr-test02.uio.no 2.6.18-308.4.1.el5 #1 SMP Wed Mar 28 01:54:56 EDT 2012 x86_64 GNU/Linux
My properties.xml looks like:
<configuration> <property name="org.apache.manifoldcf.database.maxhandles" value="100"/> <property name="org.apache.manifoldcf.crawler.threads" value="50"/> <property name="org.apache.manifoldcf.database.name" value="****"/> <property name="org.apache.manifoldcf.database.username" value="****"/> <property name="org.apache.manifoldcf.database.password" value="****"/> <property name="org.apache.manifoldcf.postgresql.hostname" value="dbpg-chaos2.uio.no"/> <property name="org.apache.manifoldcf.postgresql.ssl" value="true"/> <!-- Point to a specific logging file --> <property name="org.apache.manifoldcf.logconfigfile" value="./logging.ini"/> <!-- Tell LCF where to find the connector jars --> <libdir path="../lib/"/> <property name="org.apache.manifoldcf.salt" value="****"/> <!-- Any additional properties go here --> <property name="org.apache.manifoldcf.synchdirectory" value="../data/synchdir"/> </configuration>
