Sam Tunnicliffe commented on CASSANDRA-10738: --------------------------------------------- Ok, so the keyspaces data was converted ok, but unfortunately it looks like there is some further corruption to the {{system_schema.tables}} files. You'll need to repeat the process of re-running the conversion, but this time also remove the files from {{data/system_schema/tables-afddfb9dbc1e30688056eed6c302ba09/}} and restore the pre-upgrade snapshots of {{system/schema_columnfamilies-45f5b36024bc3f83a3631034ea4fa697/}} (that's in addition the keyspaces tables from the previous comment). > upgrading to v3.0.0 nodes crashes with > "org.apache.cassandra.serializers.MarshalException: Unexpected extraneous > bytes after map value" > --------------------------------------------------------------------------------------------------------------------------------------- > > Key: CASSANDRA-10738 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10738 > Project: Cassandra > Issue Type: Bug > Environment: ubuntu14, java8 > Reporter: Christian Sherwood > Assignee: Sam Tunnicliffe > Attachments: 1447894738468-upgrade-2.2.3-3.0.0.zip, cassv3.txt, > keyspaces-abac5682dea631c5b535b3d6cffd0fb6.zip, system_schemas.txt > > > upgrading from v.2.2.3 to v3.0.0 > restarting after upgrade crashes with either > ERROR [main] 2015-11-19 20:21:26,511 CassandraDaemon.java:702 - Exception > encountered during startup > org.apache.cassandra.serializers.MarshalException: Unexpected extraneous > bytes after map value > OR > ERROR [main] 2015-11-19 20:01:13,945 CassandraDaemon.java:702 - Exception > encountered during startup > java.lang.IllegalArgumentException: null > see attached debug and schema -- This message was sent by Atlassian JIRA (v6.3.4#6332)
