Weiwei Yang created HDFS-12082:
----------------------------------
Summary: BlockInvalidateLimit value is incorrectly set after
namenode heartbeat interval reconfigured
Key: HDFS-12082
URL: https://issues.apache.org/jira/browse/HDFS-12082
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs, namenode
Reporter: Weiwei Yang
Assignee: Weiwei Yang
HDFS-1477 provides an option to reconfigured namenode heartbeat interval
without restarting the namenode. When the heartbeat interval is reconfigured,
{{blockInvalidateLimit}} gets recounted
{code}
this.blockInvalidateLimit = Math.max(20 * (int) (intervalSeconds),
DFSConfigKeys.DFS_BLOCK_INVALIDATE_LIMIT_DEFAULT);
{code}
this doesn't honor the existing value set by {{dfs.block.invalidate.limit}}.
