------------------------------------------
Summary: Refactor the BlockScanner to use O(1) memory and use
multiple threads
Key: HDFS-7430
URL: https://issues.apache.org/jira/browse/HDFS-7430
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 2.7.0
Reporter: Colin Patrick McCabe
We should update the BlockScanner to use a constant amount of memory by keeping
track of what block was scanned last, rather than by tracking the scan status
of all blocks in memory. Also, instead of having just one thread, we should
have a verification thread per hard disk (or other volume), scanning at a
configurable rate of bytes per second.
