Luke 3.1.0 can't open an Solr index from version 3.2.0 #40

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Open an generated index from Solr 3.2.0

What is the expected output? What do you see instead?
Expected: Luke can open the index.
See: error message when opening an index: Incompatible format version: 3 
expected 2 or lower

What version of the product are you using? On what operating system?
Version: 3.1.0
OS: OS X 10.6.7

Please provide any additional information below.
It seems that Solr with version 3.2.0 is now generating the index in another 
format and luke can't work with this new index format.

I managed to get the luke 3.1-branch compiling against solr+lucene 3.2 with 
only small changes (iterator semantics must be used to read from SegmentInfos 
now) - resulting in the attached lukeall-3.2.0.jar file. Hope it is of use and 
can get some of you by until a proper official release is available.

Just happened to do the same... changes are to the ant build file and one tiny 
source change from get() to info() on line 159 of 
src/org/apache/lucene/index/IndexGate.java

Can you please tell me exactly what you've changed in the ant build file, 
because I've tried this now also:
changed in build.xml everything from 3.1.0 to 3.2.0 and in IndexGate.java get() 
to info(), then compiled it and tried to open the generated index from 
Solr-3.2.0, but again got the error message:
Incompatible format version: 3 expected 2 or lower

did you try lukeall-3.2.0.jar that simon provided above?

anyway, the build file changes were only to the version numbers (3.1.0 to 
3.2.0). They appear quite often in the file, make sure to catch them all.  And 
maybe also make sure that the lucene 3.1 jar files are deleted.

Yes, downloaded the provided one from simon and it also worked for me, but I 
wanted to try it on my own - always interested in learning new stuff.

thx a lot

I've got this exception (with the 3.2.0 jar file provided above) which means I 
can't view the document.

cast to org.apache.lucene.document.Field

the 3.2 jar reads the index fine, but then when you browse the documents, you 
get:

This error was caused by an implicit cast in a deprecated api. I fixed this in 
the upcoming 3.3.0 release. Thanks!

I'm still getting errors with r69. Luke.java has several casts to Field instead 
of Fieldable.

Actually, there are a ton of left-over references to getFields() as well. Need 
to replace with getFieldables(); e.g. export doesn't work with numeric fields.

Please try this patch and report if this works with your index.

I did not try your patch, but it looks like the same changes I've made.

This is fixed in branch_3x, and the upcoming release 3.5.0. Thanks!
