--------------------------------------------
Summary: use HDFS advisory caching to avoid caching HFiles that
are not going to be read again (because they are being compacted)
Key: HBASE-10052
URL: https://issues.apache.org/jira/browse/HBASE-10052
Project: HBase
Issue Type: Improvement
Reporter: Colin Patrick McCabe
HBase can benefit from doing dropbehind during compaction since compacted files
are not read again. HDFS advisory caching, introduced in HDFS-4817, can help
here. The right API here is {{DataOutputStream#setDropBehind}}.
