Strange. This happens after I added all documents using
IndexWriter.addDocument() function. Everything works well at that point.
I then call IndexWriter.forceMerge(1), finally IndexWriter.close(true).
The "out of memory" problem happens after I called forceMerge(1) but before
close(true).
If mer
merging binarydocvalues doesn't use any RAM, it streams the values from the
segments its merging directly to the newly written segment.
So if you have this problem, its unrelated to merging: it means you don't
have enough RAM to support all the stuff you are putting in these
binarydocvalues fields
Hi,
After finishing indexing, we tried to consolidate all segments using
forcemerge, but we continuously get out of memory error even if we
increased the memory up to 4GB.
Exception in thread "main" java.lang.IllegalStateException: this writer hit
an OutOfMemoryError; cannot complete forceMerge
