I was able to complete the repair, repairing one keyspace and cf each time.
However the last session is still shown as an active process, even if
the session has been successfully completed, this is the log:
INFO [CompactionExecutor:252] 2014-01-14 03:10:13,105

Hey folks,
I used create_column_family to create a CF but made a typo and I need to

SYSTEM_MANAGER.alter_column_family('Narrative','Instagram_Tag

Hi,
I sympathize with your issue. I recommend adding the following to your JVM
flags:
JVM_OPTS="$JVM_OPTS -XX:+PrintGCDetails"
JVM_OPTS="$JVM_OPTS -XX:+PrintGCDateStamps"
JVM_OPTS="$JVM_OPTS -XX:+PrintHeapAtGC"
JVM_OPTS="$JVM_OPTS -XX:+PrintTenuringDistribution"
JVM_OPTS="$JVM_OPTS -XX:+PrintGCAp
