------------------------------------------
Summary: ZCR should work with blocks bigger than 2 GB
Key: HDFS-5101
URL: https://issues.apache.org/jira/browse/HDFS-5101
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs-client
Reporter: Colin Patrick McCabe
Priority: Minor
Zero-copy reads should work with blocks bigger than 2 GB. This will a little
tricky, because a single ByteBuffer can only span 2 GB in Java (due to the use
of a signed 4-byte int for sizes, etc).
