Peter Schuller commented on CASSANDRA-3931: ------------------------------------------- I forgot to mention that {{describe_ring}} is using a piece of code that actually sends messages to other nodes asking for their schema, while {{gossipinfo}} is giving the information contained in the Gossiper's endpoint state map. Given that the schema seems to *actually* be propagated, I suspect this is only a gossiping propagation bug but that is not confirmed. > gossipers notion of schema differs from reality as reported by the nodes in > question > ------------------------------------------------------------------------------------ > > Key: CASSANDRA-3931 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3931 > Project: Cassandra > Issue Type: Bug > Reporter: Peter Schuller > Fix For: 1.1.0 > > > On a 1.1 cluster we happened to notice that {{nodetool gossipinfo | grep > SCHEMA}} reported disagreement: > {code} > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:b0d7bab7-c13c-37d9-9adb-8ab8a5b7215d > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:bcdbd318-82df-3518-89e3-6b72227b3f66 > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:bcdbd318-82df-3518-89e3-6b72227b3f66 > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > SCHEMA:59adb24e-f3cd-3e02-97f0-5b395827453f > {code} > However, the result of a thrift {{describe_ring}} on the cluster claims they > all agree and that {{b0d7bab7-c13c-37d9-9adb-8ab8a5b7215d}} is the schema > they have. > The schemas seem to "actually" propagate; e.g. dropping a keyspace actually > drops the keyspace. -- This message is automatically generated by JIRA.
