Examples with Scheduler org.apache.hadoop.lib.service.Scheduler used on opensource projects

Example 1 with Scheduler

use of org.apache.hadoop.lib.service.Scheduler in project hadoop by apache.

the class FileSystemAccessService method postInit.

@Override
public void postInit() throws ServiceException {
    super.postInit();
    Instrumentation instrumentation = getServer().get(Instrumentation.class);
    instrumentation.addVariable(INSTRUMENTATION_GROUP, "unmanaged.fs", new Instrumentation.Variable<Integer>() {

        @Override
        public Integer getValue() {
            return unmanagedFileSystems.get();
        }
    });
    instrumentation.addSampler(INSTRUMENTATION_GROUP, "unmanaged.fs", 60, new Instrumentation.Variable<Long>() {

        @Override
        public Long getValue() {
            return (long) unmanagedFileSystems.get();
        }
    });
    Scheduler scheduler = getServer().get(Scheduler.class);
    int purgeInterval = getServiceConfig().getInt(FS_CACHE_PURGE_FREQUENCY, 60);
    purgeTimeout = getServiceConfig().getLong(FS_CACHE_PURGE_TIMEOUT, 60);
    purgeTimeout = (purgeTimeout > 0) ? purgeTimeout : 0;
    if (purgeTimeout > 0) {
        scheduler.schedule(new FileSystemCachePurger(), purgeInterval, purgeInterval, TimeUnit.SECONDS);
    }
}
