Solr 4.3 fails to load MySQL driver
Hi,
in my attempt to migrate for m 3.6.x to 4.3.0 I stumbled upon an issue
loading the MySQL driver from the [instance]/lib dir:
Caused by: java.lang.ClassNotFoundException:
org.apache.solr.handler.dataimport.DataImportHandler
at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
at java.net.URLClassLoader$1.run(URLClassLoader.java:355)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:354)

at java.lang.Class.forName(Class.java:266)
at
org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:448)
... 18 more
To narrow it down, I use the plain example configuration with the
following changes:
- Add a dataimport requestHandler to example/conf/solrconfig.xml
(copied from a working solr 3.6.x)
- Created example/conf/data-config.xml with
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" ...
and SQL statement (both copied from a working solr 3.6.x)
- placed the current driver "mysql-connector-java-5.1.25-bin.jar" in
example/lib
As to my knowledge the lib dir is included automatically to the path. To
make sure I tried to:
- add <lib dir="./lib" /> to explicit to solrconf.xml
- add absolute path to solrarconf.xml
- changed solr.xml to use <solr persistent="true" sharedLib="lib>
All to no avail.
System Info:
- OpenJDK Runtime Environmentm 1.7.0_19
- Solr 4.3.0
- mysql-connector-java-5.1.25-bin.jar
The same configuration run fine with a solr 3.6.x on the very same machine.
Any help is appreciated!
Cheers
Chris

sorry for the confusion. I was just trying to say:
I use the example code from
solr-4.3.0/example/solr
and not from
solr-4.3.0/example/example-DIH

For solr is was recomended to place the MySQL driver in
solr_3.6.2/example/lib/ This dir is load by default in 3.6 (as I did not
add any additional lib dirs). Thats why I did this in 4.3 as well.
What's the best practice to place third party libs?
I added example/lib/ to collection1/conf/solrconfig.xml as <lib dir
Without this, the MySQL driver is not loaded according to the
org.apache.solr.core.SolrResourceLoader – Adding xxx messages

collection1/conf/solrconfig.xml has the following lib dirs by default:
<lib dir="../../../contrib/extraction/lib" regex=".*\.jar" />
<lib dir="../../../dist/" regex="solr-cell-\d.*\.jar" />
<lib dir="../../../contrib/clustering/lib/" regex=".*\.jar" />
<lib dir="../../../dist/" regex="solr-clustering-\d.*\.jar" />
<lib dir="../../../contrib/langid/lib/" regex=".*\.jar" />
<lib dir="../../../dist/" regex="solr-langid-\d.*\.jar" />
<lib dir="../../../contrib/velocity/lib" regex=".*\.jar" />
<lib dir="../../../dist/" regex="solr-velocity-\d.*\.jar" />
Looks the same to me as in 3.6.

That means I have to configure the dataimporthandler manually in 4.3? If
yes, this is the root of all problems ...

still does not load.

i'm totally confused ... DIH == DataImportHandler ... it's just an
acronym, you say you aren't using DIH, but you are having a problem
loading DIH, so DIH is used in your configs.
: I include the full trace back to clarify my problem (hopefully)
...

...ok, for starters this makes no sense, and may be the cause of
some problems. you aparently have your collection1 configs setup to load
all of the classes from the /home/solr/solr-4.3.0/example/example/lib
directory as part of the collection1 classloader.
you really don't want to do that. It will most likeley cause you all
sorts of problems, even if it's unrelated to the current problem.
Second, note in particular all of the lines that look like that line above
-- specifically lines that say "org.apache.solr.core.SolrResourceLoader -
Addming XXXX to classloader". besides the ones refering to
/home/solr/solr-4.3.0/example/lib/ (which is almost certainly not what you
want) you then have a bunch refering to contrib/extraction and
contrib/langid, and contrib/velocity -- all of which is great, those
plugins and their dependencies are now available to use.
but no where does it ever say anything about adding
contrib/dataimporthandler jars to the classloader.
which means your config isn't setup to load any of hte dataimporthandler
jars as plugins
which means when it's done loading plugins, and it starts to initialize
things like RequestHandlers, and it finds a refrence to the
DataImportHandler, it doesn't know what that means...
: Caused by: java.lang.ClassNotFoundException:
: org.apache.solr.handler.dataimport.DataImportHandler
if you look at the 4.3 DIH examples, you'll note that
the only solrconfig.xml files that mention "DataImportHandler" also
include lib directives like the following in order to load
dataimporthandler as a plugin...
<lib dir="../../../../dist/" regex="solr-dataimporthandler-.*\.jar" />
...
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">

I corrected myself in my last mail: the MySQL driver IS loaded (thanx
for pointing out to me where to look).

I only SUSPECT of the MySQL driver being the culprit for the
dataimporthandler jar is not getting loaded. Not sure!

I am not using DIH. IMHO its just the plain example code in
solr-4.3.0/example/solr/collection1/ that is being called.

Re: Solr 4.3 fails to load MySQL driver
Posted by Chris Hostetter <ho...@fucit.org>.
: in my attempt to migrate for m 3.6.x to 4.3.0 I stumbled upon an issue loading
: the MySQL driver from the [instance]/lib dir:
:
: Caused by: java.lang.ClassNotFoundException:
: org.apache.solr.handler.dataimport.DataImportHandler
one of us is mistaken by what that error means. you say it means that
the MySQL driver isn't being loaded, but nothing in your mail suggests
to me that there is a problem loading hte MySql driver. what i see is
that Solr can't seem to load the DIH class, suggesting that the
dataimporthandler jar is not getting loaded.
There may or nay not also be a problem loading the MySQL driver, but
nothing is even going to attempt to do so unless Solr can successfully
construct an instance of the DataImportHandler.
So unless there are more details to your error that start mentioning the
MySql classes, i would check your lib settings for loading the DIH jars
and make sure those are right.

Hi,
thanx for pointing this out to me.
1152 [coreLoadExecutor-3-thread-1] INFO org.apache.solr.core.SolrConfig

The mysql-connector-java DOES get loaded, but is not available to
org.apache.solr.core.SolrResourceLoader.findClass
Has something changed for the syntax creating a dataimport handler?
solrconfig.xml:

I use this configuration successfully with 3.6

Re: Solr 4.3 fails to load MySQL driver
Posted by Jack Krupansky <ja...@basetechnology.com>.
Check the Solr log on startup - it will explicitly state which lib
directories/files will be used. Make sure they agree with where the DIH jars
reside. Keep in mind that the directory structure of Solr changed - use the
lib from 4.3 solrconfig.
Try to use DIH in the standard Solr 4.3 example first. Then mimic that in
your customization.

To narrow it down, I use the plain example configuration with the
following changes:
- Add a dataimport requestHandler to example/conf/solrconfig.xml
(copied from a working solr 3.6.x)
- Created example/conf/data-config.xml with
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" ...
and SQL statement (both copied from a working solr 3.6.x)
- placed the current driver "mysql-connector-java-5.1.25-bin.jar" in
example/lib
As to my knowledge the lib dir is included automatically to the path. To
make sure I tried to:
- add <lib dir="./lib" /> to explicit to solrconf.xml
- add absolute path to solrarconf.xml
- changed solr.xml to use <solr persistent="true" sharedLib="lib>
All to no avail.
System Info:
- OpenJDK Runtime Environmentm 1.7.0_19
- Solr 4.3.0
- mysql-connector-java-5.1.25-bin.jar
The same configuration run fine with a solr 3.6.x on the very same machine.
Any help is appreciated!

The best thing to do is take the lib directives out of solrconfig.xml
and put your extra jars in ${solr.solr.home}/lib, where solr.solr.home
is the directory where solr.xml lives. NB: There might be two solr.xml
files in your setup, but if there are, one of them will tell your
servlet container how to start solr, the correct file tells solr about
cores.
Normally, you can set up another global lib directory, absolute or
relative to solr.solr.home, with the sharedLib attribute in solr.xml,
but that doesn't work in 4.3.0 - only ${solr.solr.home}/lib works in
that specific version. Here's the bug report:
https://issues.apache.org/jira/browse/SOLR-4791
I discovered another glitch last night in the 4.4 development version
and filed a bug report, but I've been informed that I've been doing it
wrong for the last couple of years:
https://issues.apache.org/jira/browse/SOLR-4852
Thanks,
Shawn
