Can you show us your code around the following line ?
CDCTrigger.TriggerForModification.prePut(TriggerForModification.java:51)
The error was due to:
public HTableInterface getTable(byte[] tableName, ExecutorService pool)
throws IOException {
if (managed) {
throw new IOException("The connection has to be unmanaged.");
}
Cheers
