-------------------------------
Summary: IndexSizeEstimator NullPointerException
Key: SOLR-13694
URL: https://issues.apache.org/jira/browse/SOLR-13694
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Hoss Man
Assignee: Andrzej Bialecki
Jenkins found a reproducible seed for trigging an NPE in IndexSizeEstimatorTest
Based on a little experimental tracing i did, this might be a real bug in
IndexSizeEstimator? ... it's calling close on StoredFieldsReader instances it
gets from the CodecReader -- but AFAICT from the docs/code i'm not certain if
it should be doing this. It appears the expectation is that this is direct
access to the internal state, that will automatically be closed when the
CodecReader is closed.
ie: IndexSizeEstimator is closing StoredFieldsReader pre-maturely, causing it
to be unusbale on the next iteration.
(I didn't dig in far enough to guess if there are other places in the
IndexSizeEstimator code that are closing CodecReader internals prematurely as
well, or just in this situation ... it's also not clear if this only causes
failures because this seed uses SimpleTextCodec, and other codecs are more
forgiving -- or if something else about the index(es) generated for this seed
are what cause the problem to manifest)
