------------------------------------------
Summary: IndexWriter gets angry at leftover temp files (e.g. from
BKD)
Key: LUCENE-6886
URL: https://issues.apache.org/jira/browse/LUCENE-6886
Project: Lucene - Core
Issue Type: Bug
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: Trunk
I was trying to run performance test for the new dimensional values and hit
this crazy exception:
{noformat}
Exception in thread "main" java.lang.NumberFormatException: For input string:
"5976285795"
at
java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)

org.apache.lucene.index.IndexFileDeleter.inflateGens(IndexFileDeleter.java:287)

perf.IndexAndSearchOpenStreetMaps.createIndex(IndexAndSearchOpenStreetMaps.java:64)
at
perf.IndexAndSearchOpenStreetMaps.main(IndexAndSearchOpenStreetMaps.java:162)
{noformat}
It happened because I killed my indexing process while BKD was writing temp
files. On starting up again, IW would have removed these unreferenced files,
except inflateGens got confused by their names.
This bug only happens on trunk.
