----------------------------------------
Summary: ConcurrentModificationException in nodetool
upgradesstables
Key: CASSANDRA-13718
URL: https://issues.apache.org/jira/browse/CASSANDRA-13718
Project: Cassandra
Issue Type: Bug
Environment: Cassandra 3.11 on Linux
Reporter: Hannu Kröger
When upgrading from 2.2.8 to Cassandra 3.11 we were able to upgrade all other
sstables except 1 file on 3 nodes (out of 4). Those are related to 2 different
tables.
Upgrading sstables fails with ConcurrentModificationException.
