Andy Isaacson created HDFS-3815:
-----------------------------------
Summary: CorruptBlocks documentation is misleading
Key: HDFS-3815
URL: https://issues.apache.org/jira/browse/HDFS-3815
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 2.0.0-alpha
Reporter: Andy Isaacson
Assignee: Andy Isaacson
Priority: Minor
In {{FSNamesystem.java}} we have
{code}
/** Returns number of blocks with corrupt replicas */
@Metric({"CorruptBlocks", "Number of blocks with corrupt replicas"})
{code}
The CorruptBlocks metric does not count blocks, it counts replicas.
Unfortunately many places depend on the name {{CorruptBlocks}} so changing the
name would be incompatible. But we can at least update the Javadoc and
description to explain the misnomer.
