DENG FEI created SPARK-25070:
--------------------------------
Summary: BlockFetchingListener#onBlockFetchSuccess throw
"java.util.NoSuchElementException: key not found: shuffle_8_68_113" on
ShuffleBlockFetcherIterator caused stage hang long time
Key: SPARK-25070
URL: https://issues.apache.org/jira/browse/SPARK-25070
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.2.0
Reporter: DENG FEI
The task fetch shuffle block success, but failed onBlockFetchSuccess, lead the
task hang long time and speculate as false.
The log is below:
