-----------------------------------------
Summary: Document - Disabling the Lazy persist file scrubber.
Key: HDFS-12987
URL: https://issues.apache.org/jira/browse/HDFS-12987
Project: Hadoop HDFS
Issue Type: Bug
Components: documentation, hdfs
Reporter: Karthik Palanisamy
Assignee: Karthik Palanisamy
Priority: Trivial
LazyPersistFileScrubber will be disabled if scrubber interval configured to
zero. But the document was incorrect - "Set it to a negative value to disable
this behavior".
Namenode will not start if we set to negative value. We have another strong
check to prevent it.
{code:java}
if (this.lazyPersistFileScrubIntervalSec < 0) {
throw new IllegalArgumentException(
DFS_NAMENODE_LAZY_PERSIST_FILE_SCRUB_INTERVAL_SEC
+ " must be zero (for disable) or greater than zero.");
}
{code}
This seems reflected due to
[HDFS-8276|https://issues.apache.org/jira/browse/HDFS-8276]
