Hello, I'm trying to upgrade a Solr 4.6 index to Solr 6. The upgrade does fail with an error.
I tried to check the index with org.apache.lucene.index.CheckIndex using this command: java -cp lucene-core-5.5.4.jar:lucene-backward-codecs-5.5.4.jar -ea:org.apache.lucene... org.apache.lucene.index.CheckIndex ./[PATH-TO-INDEX]/data/index The check fail with this error: Opening index @ ./[PATH-TO-INDEX]/data/index > > ERROR: could not read any segments file in directory > java.lang.IllegalArgumentException: Illegal initial capacity: -16777216 > at java.util.HashMap.<init>(HashMap.java:448) > at java.util.HashMap.<init>(HashMap.java:467) > at > org.apache.lucene.index.SegmentInfos.readCommit(SegmentInfos.java:393) > at > org.apache.lucene.index.CheckIndex.checkIndex(CheckIndex.java:488) > at org.apache.lucene.index.CheckIndex.doCheck(CheckIndex.java:2407) > at org.apache.lucene.index.CheckIndex.doMain(CheckIndex.java:2309) > at org.apache.lucene.index.CheckIndex.main(CheckIndex.java:2235) > I tried this with Cygwin and the Windows 10 Ubuntu subsystem with the same result. Any ideas? Best Moritz
