Andrew Or created SPARK-12062:
---------------------------------
Summary: Master rebuilding historical SparkUI should be
asynchronous
Key: SPARK-12062
URL: https://issues.apache.org/jira/browse/SPARK-12062
Project: Spark
Issue Type: Bug
Components: Deploy
Affects Versions: 1.0.0
Reporter: Andrew Or
When a long-running application finishes, it takes a while (sometimes minutes)
to rebuild the SparkUI. However, in Master.scala this is currently done within
the RPC event loop, which runs only in 1 thread. Thus, in the mean time no
other applications can register with this master.
