----------------------------
Summary: Fix infinite CPU spin loop in ECBlockInputStream
Key: HDDS-14724
URL: https://issues.apache.org/jira/browse/HDDS-14724
Project: Apache Ozone
Issue Type: Bug
Components: Ozone Client
Affects Versions: 2.1.0
Reporter: Jayer
Assignee: Jayer
Attachments: spark-executor-cpu-spin-jstack.txt
Currently, ECBlockInputStream#readFromStream only checks if actualRead == -1
(EOF). If 0 bytes are returned while expectedRead > 0, the stream fails to
advance its position but remains in the while loop, causing an infinite CPU
spin and thread starvation.
