Jordan West updated CASSANDRA-19578: ------------------------------------ Bug Category: Parent values: Correctness(12982)Level 1 values: Recoverable Corruption / Loss(12986) Complexity: Normal Discovered By: User Report Severity: Critical Status: Open (was: Triage Needed) > Concurrent equivalent schema updates lead to unresolved disagreement > -------------------------------------------------------------------- > > Key: CASSANDRA-19578 > URL: https://issues.apache.org/jira/browse/CASSANDRA-19578 > Project: Cassandra > Issue Type: Bug > Components: Cluster/Schema > Reporter: Chris Lohfink > Priority: Normal > > As part of CASSANDRA-17819 a check for empty schema changes was added to the > updateSchema. This only looks at the _logical_ schema difference of the > schemas, but the changes made to the system_schema keyspace are the ones that > actually are involved in the digest. > If two nodes issue the same CREATE statement the difference from the > keyspace.diff would be empty but the timestamps on the mutations would be > different, leading to a pseudo schema disagreement which will never resolve > until resetlocalschema or nodes being bounced. > Only impacts 4.1 > test and fix : > https://github.com/clohfink/cassandra/commit/ba915f839089006ac6d08494ef19dc010bcd6411 -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
