mukund-thakur opened a new pull request, #4862:
URL: https://github.com/apache/hadoop/pull/4862
part of HADOOP-18103.
While merging the ranges in CheckSumFs, they are rounded up based on the
value of checksum bytes size which leads to some ranges crossing the EOF
thus they need to be fixed else it will cause EOFException during actual
reads.
