-------------------------------------------
Summary: Detect index corruption for all files on replication
Key: SOLR-8119
URL: https://issues.apache.org/jira/browse/SOLR-8119
Project: Solr
Issue Type: Improvement
Components: replication (java)
Reporter: Shalin Shekhar Mangar
Fix For: Trunk, 5.4
Lucene writes checksums for large files but they aren't verified until a merge
is necessary because it'd be too costly to go through the entire bytes. Only
truncation of such files is checked during open. However, index replication is
one activity that has to go through the entire file anyway so we can be more
aggressive than Lucene in validating the checksum.
I propose that we validate all files, large and small, during replication.
