-------------------------------
Summary: Fetchers should be more robust to corrupted inputs
Key: TEZ-3912
URL: https://issues.apache.org/jira/browse/TEZ-3912
Project: Apache Tez
Issue Type: Bug
Reporter: Jason Lowe
I recently saw a case where a bad node in the cluster produced corrupted
shuffle data that caused the codec to throw IllegalArgumentException when
trying to fetch. Fetchers currently only handle IOException and InternalError,
and any other type of exception will cause the entire task to be torn down. We
should consider catching Exception like MapReduce does to be more robust in
light of other types of errors coming from the codec and allow retries to occur.
