--------------------------------------------
Summary: ConcurrentModificationException while executing 'nodetool
cleanup'
Key: CASSANDRA-8537
URL: https://issues.apache.org/jira/browse/CASSANDRA-8537
Project: Cassandra
Issue Type: Bug
Components: Tools
Environment: Debian 7.7, Oracle JRE 1.7.0_72
Reporter: Noureddine Chatti
Fix For: 2.1.2
After adding a new node to an existing cluster (7 already started nodes), and
waiting a few minutes to be sure that data migration to the new node is
completed, I began to use the command nodetool cleanup sequentially on each old
node. When I issued this command on the third node, after a few minutes I got a
ConcurrentModificationException.
~$ nodetool cleanup
error: null
