Hey All, On a Solr server running 4.10.2 with three cores, two return the expected info from /solr/admin/cores?wt=json but the third is missing userData and lastModified.
The first (artists) and third (tracks) cores from the linked screenshot are the ones I care about. Unfortunately, the third (tracks) is the one missing lastModified. As far as I can see, that comes from: https://github.com/apache/lucene-solr/blob/lucene_solr_4_10_2/solr/core/src/java/org/apache/solr/handler/admin/LukeRequestHandler.java#L568 I can't trace back to see what would possible cause getUserData() to return an empty Object, but that appears to be what is happening? For these severs, indexes that are pre-optimized are shipped over to the server and the server is re-started... nothing is actually ever committed on these live servers. This should behave exactly the same for artists and tracks, even though tracks is the one always missing lastUpdated. Here's the output in img format, I'll paste the full JSON[1] below: http://monosnap.com/image/XMyAfk5z3AvHgY39m0qAKAGlc3RACI.png I'd like to be able to provide access to clients to grab lastUpdated time for both indices so that they can see how old/stale the data they are getting results back from is... ...alternately, is there any other way to expose easily how old (last modified time?) the index for a core is? Thanks, Aaron 1: Full JSON ---snip--- { "responseHeader": { "status": 0, "QTime": 10 }, "defaultCoreName": "collection1", "initFailures": { }, "status": { "artists": { "name": "artists", "isDefaultCore": false, "instanceDir": "/opt/solr/search/solr/artists/", "dataDir": "/opt/solr/search/solr/artists/", "config": "solrconfig.xml", "schema": "schema.xml", "startTime": "2015-03-24T14:12:23.667Z", "uptime": 7335696, "index": { "numDocs": 3360380, "maxDoc": 3360380, "deletedDocs": 0, "indexHeapUsageBytes": 63366952, "version": 421, "segmentCount": 1, "current": true, "hasDeletions": false, "directory": "org.apache.lucene.store.MMapDirectory:MMapDirectory@/opt/solr/search/solr/artists/index lockFactory=NativeFSLockFactory@/opt/solr/search/solr/artists/index", "userData": { "commitTimeMSec": "1427133705908" }, "lastModified": "2015-03-23T18:01:45.908Z", "sizeInBytes": 25341305528, "size": "23.6 GB" } }, "banana-int": { "name": "banana-int", "isDefaultCore": false, "instanceDir": "/opt/solr/search/solr/banana-int/", "dataDir": "/opt/solr/search/solr/banana-int/data/", "config": "solrconfig.xml", "schema": "schema.xml", "startTime": "2015-03-24T14:12:22.895Z", "uptime": 7336472, "index": { "numDocs": 3, "maxDoc": 3, "deletedDocs": 0, "indexHeapUsageBytes": 17448, "version": 135, "segmentCount": 3, "current": true, "hasDeletions": false, "directory": "org.apache.lucene.store.NRTCachingDirectory:NRTCachingDirectory(MMapDirectory@/opt/solr/search/solr/banana-int/data/index lockFactory=NativeFSLockFactory@/opt/solr/search/solr/banana-int/data/index; maxCacheMB=48.0 maxMergeSizeMB=4.0)", "userData": { "commitTimeMSec": "1412796723183" }, "lastModified": "2014-10-08T19:32:03.183Z", "sizeInBytes": 16196, "size": "15.82 KB" } }, "tracks": { "name": "tracks", "isDefaultCore": false, "instanceDir": "/opt/solr/search/solr/tracks/", "dataDir": "/opt/solr/search/solr/tracks/", "config": "solrconfig.xml", "schema": "schema.xml", "startTime": "2015-03-24T14:12:23.656Z", "uptime": 7335713, "index": { "numDocs": 53268126, "maxDoc": 53268126, "deletedDocs": 0, "indexHeapUsageBytes": 517650552, "version": 100, "segmentCount": 1, "current": true, "hasDeletions": false, "directory": "org.apache.lucene.store.MMapDirectory:MMapDirectory@/opt/solr/search/solr/tracks/index lockFactory=NativeFSLockFactory@/opt/solr/search/solr/tracks/index", "userData": { }, "sizeInBytes": 122892905007, "size": "114.45 GB" } } } } ---snip---
