-----------------------------------
Summary: EC Checksum throws IllegalArgumentException because the
buffer limit is negative
Key: HDDS-11482
URL: https://issues.apache.org/jira/browse/HDDS-11482
Project: Apache Ozone
Issue Type: Bug
Reporter: Aswin Shakil
Assignee: Aswin Shakil
The parity checksum bytes calculation for EC stripe checksum should be based on
each stripe's first chunk's length. But right now it is calculated only on the
first stripe's chunk length which results in incorrect results and, in many
cases causes the byte buffer limit to become negative.
