> bq. but I think it is simple enough to change the meaning of the value so that zero means
'never scrub'. Let me post an updated patch.
> As discussed in [HDFS-6929|https://issues.apache.org/jira/browse/HDFS-6929], scrubber
should be disable if *dfs.namenode.lazypersist.file.scrub.interval.sec* is zero.
> Currently namenode startup is failing if interval configured zero
> {code}
> 2015-04-27 23:47:31,744 ERROR org.apache.hadoop.hdfs.server.namenode.FSNamesystem: FSNamesystem
initialization failed.
> java.lang.IllegalArgumentException: dfs.namenode.lazypersist.file.scrub.interval.sec
must be non-zero.
> at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.<init>(FSNamesystem.java:828)
> {code}
