Hive replication failure
DLM out of memory
Replication policy operations
Monitoring replication
Ensure that the frequency is set so that a job finishes before the next job starts. Jobs based on the same policy cannot overlap.
Policies page
You can check job status from several places in the DLM UI.
Tuning replication policy (advanced options)
Specify bandwidth per map, in MBps. Each map is restricted to consume only the specified bandwidth. This is not always exact. The map throttles back its bandwidth consumption during a copy in such a way that the net bandwidth used tends towards the specified value.
Update replication policy
You can edit some settings in your policies to better align with changing requirements. For example, you might want to change the frequency of a policy depending on the data size and importance of the data being replicated.
Browsing data directory
Any user with access to the DLM UI has the ability to browse, within the DLM UI, the folder structure of any clusters enabled for DLM.
