Subject RE: lots of DigestMismatchException in cassandra3
Date Tue, 22 Nov 2016 06:30:46 GMT
Hi Kurt,
Thank you for the information, but the error “Corrupt empty row found in unfiltered partition”
seems not related to the “Mismatch”; the time they occurred didn’t match. We use “QUORUM”
consistency level for both read and write and I didn’t notice any failed writing in the
log. Any other cause you can think of?  Would it cause performance issue when lots of this
“Mismatch” happened?

Regards, Adeline

Actually, just saw the error message in those logs and what you're looking at is probably
https://issues.apache.org/jira/browse/CASSANDRA-12694<https://urldefense.proofpoint.com/v2/url?u=https-3A__issues.apache.org_jira_browse_CASSANDRA-2D12694&d=CwMFaQ&c=4ZIZThykDLcoWk-GVjSLm9hvvvzvGv0FLoWSRuCSs5Q&r=552xSDXEzKpvsyZM5wpE0TGEUDzVsX35L-K72hRjpLc&m=Km5uRGlDf2EjQFx7dbIrLzNfL6khh5OKA2sJk59l8-w&s=tMf24yohd0jRGCBo_pzYdRMw52h3NCImPOGXjy1SAsc&e=>

That's a debug message. From the sound of it, it's triggered on read where there is a digest
mismatch between replicas. As to whether it's normal, well that depends on your cluster. Are
the nodes reporting lots of dropped mutations and are you writing at <QUORUM?
