Lucene 3.4.0 Merging
Hi
I have 3 solr3.4.0 indexes i want to merge them, after searching on web i found that there are two ways to do it as
1. Using Lucene Merge tool.
2. Merging through core admin
i am using the 1st method for this i have downloaded lucene 3.4.0 and unpack it and then run following command on command prompt
java -cp d:/lucene/lucene-core-3.4.0.jar:./contrib/misc/lucene-misc-3.4.0.jarorg/apache/lucene/misc/IndexMergeTool ./newindex ./app1/solr/data/index ./app2/solr/data/indexbut unfortunately it gives me following exception
Exception in thread "Main Thread" java.lang.NoClassDefFoundError:
org/apache/lucene/misc/IndexMergeTool
can any body guide me about this
Regards
Ahsan

Hi Steve
Thanks a lot for all the help,before reading your last response, I have created a new java application in net beans and add both the jars as library to the newly created application,
and in the main method I have called IndexMergeTool.main and pass all command line arguments to this method, and this work fine. But this process start optimizing index after merging and that is taking a long time, can u tell me how can i control this procedure by some parameter,
Regards
Ahsan

Ahsan,
Maybe one or both of the Lucene jar files are not where your classpath says they are? Try copying them into the current directory, then adjusting the classpath entries, like so:
java -cp lucene-core-3.4.0.jar;lucene-misc-3.4.0.jar org/apache/lucene/misc/IndexMergeTool ./newindex ./app1/solr/data/index ./app2/solr/data/index
If that doesn't work, tell us about your environment: operating system, java version and vendor.

Ahsan,
You have one other problem: on windows, you should use ";" instead of ":" to separate the classpath entries - also, it's good to be in the habit of enclosing windows paths in quotation marks, in case one of the sub-directories has a space in its name:
java -cp "d:/lucene/lucene-core-3.4.0.jar;./contrib/misc/lucene-misc-3.4.0.jar" org/apache/lucene/misc/IndexMergeTool ./newindex ./app1/solr/data/index ./app2/solr/data/index

Hi Ahson,
The wiki page you got your cmdline invocation from <http://wiki.apache.org/solr/MergingSolrIndexes> was missing a space character between the classpath and "org/apache/lucene/misc/IndexMergeTool". I've just updated that page.
