------------------------------------
Summary: Change the default value for
dfs.namenode.replication.pending.timeout-sec from -1 to 300
Key: HDFS-10219
URL: https://issues.apache.org/jira/browse/HDFS-10219
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Akira AJISAKA
Priority: Minor
The default value for "dfs.namenode.replication.pending.timeout-sec"
({{DFS_NAMENODE_REPLICATION_PENDING_TIMEOUT_SEC_DEFAULT}}) is -1, but the
timeout is 5 minutes by default.
{code:title=BlockManager.java}
pendingReplications = new PendingReplicationBlocks(conf.getInt(
DFSConfigKeys.DFS_NAMENODE_REPLICATION_PENDING_TIMEOUT_SEC_KEY,
DFSConfigKeys.DFS_NAMENODE_REPLICATION_PENDING_TIMEOUT_SEC_DEFAULT) *
1000L);
{code}
{code:title=PendingReplicationBlocks.java}
private long timeout = 5 * 60 * 1000;
private final static long DEFAULT_RECHECK_INTERVAL = 5 * 60 * 1000;
PendingReplicationBlocks(long timeoutPeriod) {
if ( timeoutPeriod > 0 ) {
this.timeout = timeoutPeriod;
}
pendingReplications = new HashMap<>();
timedOutItems = new ArrayList<>();
}
{code}
I'm thinking we can change
{{DFS_NAMENODE_REPLICATION_PENDING_TIMEOUT_SEC_DEFAULT}} from -1 to 300 for
improving readability.
