Subject [jira] [Commented] (CASSANDRA-12203) AssertionError on compaction after upgrade (2.1.9 -> 3.7)
Date Tue, 30 Aug 2016 22:39:21 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12203?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15450347#comment-15450347
] 

Adam Patacchiola commented on CASSANDRA-12203:
----------------------------------------------

I'm seeing same issue, one table affected out of 6. Schema looks like:

CREATE TABLE chatmessages (
  username    varchar,
  spotname    varchar,
  id          varint,
  iv          varchar,
  fromuser        varchar,
  fromversion varchar,
  touser          varchar,
  toversion   varchar,
  datetime    timestamp,
  data        varchar,
  mimetype    varchar,
  datasize    int,
  shareable   boolean,
  hashed    boolean,
  PRIMARY KEY (username, spotname, id)
);

> After upgrading a Cassandra cluster from 2.1.9 to 3.7, one column family (using SizeTieredCompaction)
repeatedly and continuously failed compaction (and thus also repair) across the cluster, with
all nodes producing the following errors in the logs:
