-----------------------------------
Summary: Fix the order of the parameters in DFSConfigKeys
Key: HDFS-7732
URL: https://issues.apache.org/jira/browse/HDFS-7732
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 2.6.0
Reporter: Akira AJISAKA
Priority: Trivial
In DFSConfigKeys.java, there are some parameters between
{{DFS_CLIENT_READ_SHORTCIRCUIT_BUFFER_SIZE_KEY}} and
{{DFS_CLIENT_READ_SHORTCIRCUIT_BUFFER_SIZE_DEFAULT}}.
{code}
public static final String DFS_CLIENT_READ_SHORTCIRCUIT_BUFFER_SIZE_KEY =
"dfs.client.read.shortcircuit.buffer.size";
public static final String
DFS_CLIENT_READ_SHORTCIRCUIT_STREAMS_CACHE_SIZE_KEY =
"dfs.client.read.shortcircuit.streams.cache.size";
public static final int
DFS_CLIENT_READ_SHORTCIRCUIT_STREAMS_CACHE_SIZE_DEFAULT = 256;
public static final String
DFS_CLIENT_READ_SHORTCIRCUIT_STREAMS_CACHE_EXPIRY_MS_KEY =
"dfs.client.read.shortcircuit.streams.cache.expiry.ms";
public static final long
DFS_CLIENT_READ_SHORTCIRCUIT_STREAMS_CACHE_EXPIRY_MS_DEFAULT = 5 * 60 * 1000;
public static final int DFS_CLIENT_READ_SHORTCIRCUIT_BUFFER_SIZE_DEFAULT =
1024 * 1024;
{code}
The order should be corrected as
{code}
public static final String DFS_CLIENT_READ_SHORTCIRCUIT_BUFFER_SIZE_KEY =
"dfs.client.read.shortcircuit.buffer.size";
public static final int DFS_CLIENT_READ_SHORTCIRCUIT_BUFFER_SIZE_DEFAULT =
1024 * 1024;
public static final String
DFS_CLIENT_READ_SHORTCIRCUIT_STREAMS_CACHE_SIZE_KEY =
"dfs.client.read.shortcircuit.streams.cache.size";
public static final int
DFS_CLIENT_READ_SHORTCIRCUIT_STREAMS_CACHE_SIZE_DEFAULT = 256;
public static final String
DFS_CLIENT_READ_SHORTCIRCUIT_STREAMS_CACHE_EXPIRY_MS_KEY =
"dfs.client.read.shortcircuit.streams.cache.expiry.ms";
public static final long
DFS_CLIENT_READ_SHORTCIRCUIT_STREAMS_CACHE_EXPIRY_MS_DEFAULT = 5 * 60 * 1000;
{code}
