-### ~Another notable item here~ (affects ~versions~)
+### Updated Master Metrics to include FATE metrics.
+
+Added master metrics to provide a snapshot of current FATE operations.  The metrics added:
++ the number of current FATE transactions in progress, 
++ the count of child operations that have occurred on the zookeeper FATE node
++ a count of zookeeper connection errors when the snapshot is taken.  
+
+The number of child operations provides a light-weight surrogate for FATE transaction 
+progression between snapshots. The metrics are controlled with the following properties:
+
+* master.fate.metrics.enabled - default to _false_ preserve current metric reporting
+* master.fate.metrics.min.update.interval - default to _60s_ - there is a hard limit of 10s.
+
+When enabled, the metrics are published to JMX and can optionally be configured using standard 
+hadoop metrics2 configuration files.

+This created unnecessary contention with other operations like scan and 
+bulk imports.  For {% ghi 1031 %} the the synchronization was removed
+by {% ghi 1032 %}.
