-------------------------------------
Summary: add distributed countdown latch to cluster coordinator
Key: DRILL-270
URL: https://issues.apache.org/jira/browse/DRILL-270
Project: Apache Drill
Issue Type: Bug
Reporter: Steven Phillips
Assignee: Steven Phillips
In OrderedPartitionRecordBatch, currently we use an AtomicNumber to keep track
of how many fragments have finished sampling. Each fragment polls and sleeps
until a certain fraction of the total number is reached.
We would prefer to have a distributed CountDown latch for this purpose.
