Description

In my hadoop cluster :
set yarn.timeline-service.generic-application-history.enabled=true;
set yarn.timeline-service.generic-application-history.store-class=org.apache.hadoop.yarn.server.applicationhistoryservice.FileSystemApplicationHistoryStore;
set yarn.timeline-service.generic-application-history.fs-history-store.uri=/user/yarn/timeline/generic_history;

hdfs dfs -count /user/yarn/timeline/generic_history/ApplicationHistoryDataRoot
           1      3150832 82436180812 
the number of files in it will increase to the limit of dfs.namenode.fs-limits.max-directory-items=3200000 in less than one month and increase too fast.Now the files were cleaned  manually. Does have any ttl suggestions to clean automatically ？what should i do?
