Hey I have a 2.11.4 cluster with tables that are defined with twcs, using jeff's jar
https://github.com/jeffjirsa/twcs All working great, but now I want to upgrade to 3.11, and I have a problem, cassandra won't start, it fails on the following error ERROR [main] 2020-07-09 13:30:29,823 CassandraDaemon.java:774 - Exception encountered during startup java.lang.NoClassDefFoundError: org/apache/cassandra/io/sstable/SSTableReader at java.lang.Class.getDeclaredMethods0(Native Method) ~[na:1.8.0-zing_19.12.102.0] at java.lang.Class.privateGetDeclaredMethods(Class.java:2701) ~[na:1.8.0-zing_19.12.102.0] at java.lang.Class.privateGetMethodRecursive(Class.java:3048) ~[na:1.8.0-zing_19.12.102.0] at java.lang.Class.getMethod0(Class.java:3018) ~[na:1.8.0-zing_19.12.102.0] at java.lang.Class.getMethod(Class.java:1784) ~[na:1.8.0-zing_19.12.102.0] at org.apache.cassandra.schema.LegacySchemaMigrator.compactionFromRow(LegacySchemaMigrator.java:558) ~[apache-cassandra-3.11.7.jar:3.11.7] at org.apache.cassandra.schema.LegacySchemaMigrator.decodeTableParams(LegacySchemaMigrator.java:493) ~[apache-cassandra-3.11.7.jar:3.11.7] at org.apache.cassandra.schema.LegacySchemaMigrator.decodeTableMetadata(LegacySchemaMigrator.java:381) ~[apache-cassandra-3.11.7.jar:3.11.7] at org.apache.cassandra.schema.LegacySchemaMigrator.readTableMetadata(LegacySchemaMigrator.java:274) ~[apache-cassandra-3.11.7.jar:3.11.7] at org.apache.cassandra.schema.LegacySchemaMigrator.readTable(LegacySchemaMigrator.java:245) ~[apache-cassandra-3.11.7.jar:3.11.7] at org.apache.cassandra.schema.LegacySchemaMigrator.lambda$readTables$7(LegacySchemaMigrator.java:238) ~[apache-cassandra-3.11.7.jar:3.11.7] at java.util.ArrayList.forEach(ArrayList.java:1257) ~[na:1.8.0-zing_19.12.102.0] at org.apache.cassandra.schema.LegacySchemaMigrator.readTables(LegacySchemaMigrator.java:238) ~[apache-cassandra-3.11.7.jar:3.11.7] at org.apache.cassandra.schema.LegacySchemaMigrator.readKeyspace(LegacySchemaMigrator.java:187) ~[apache-cassandra-3.11.7.jar:3.11.7] at org.apache.cassandra.schema.LegacySchemaMigrator.lambda$readSchema$4(LegacySchemaMigrator.java:178) ~[apache-cassandra-3.11.7.jar:3.11.7] at java.util.ArrayList.forEach(ArrayList.java:1257) ~[na:1.8.0-zing_19.12.102.0] at org.apache.cassandra.schema.LegacySchemaMigrator.readSchema(LegacySchemaMigrator.java:178) ~[apache-cassandra-3.11.7.jar:3.11.7] at org.apache.cassandra.schema.LegacySchemaMigrator.migrate(LegacySchemaMigrator.java:78) ~[apache-cassandra-3.11.7.jar:3.11.7] at org.apache.cassandra.service.CassandraDaemon.setup(CassandraDaemon.java:263) [apache-cassandra-3.11.7.jar:3.11.7] (This is with the jar in place, if the jar is not there there is an error about unknown compaction startegy) I know I can convert the table to a regular size tier before the upgrade, but I would like to avoid this, as it will merge a lot of sstables into one. Has anybody upgraded a cluster with tables defined like this? Is there maybe another way to make the jar compatible with 3.X just for the sake of the upgrade so I can start my server and then move to the built in twcs. Gil
