<description>In master side, this config is the period used for FS related behaviors:
checking if hdfs is out of safe mode, setting or checking hbase.version file,
setting or checking hbase.id file. Using default value should be fine.
In regionserver side, this config is used in several places: flushing check interval,
compaction check interval, wal rolling check interval. Specially, admin can tune
flushing and compaction check interval by hbase.regionserver.flush.check.period
and hbase.regionserver.compaction.check.period. (in milliseconds)</description>
