Zhijie Shen commented on YARN-2900:
-----------------------------------
I think you were still using the old FS history store.
{code}
Caused by: java.io.IOException: History file for application
application_1417818619773_0002 is not found
at
org.apache.hadoop.yarn.server.applicationhistoryservice.FileSystemApplicationHistoryStore.getHistoryFileReader(FileSystemApplicationHistoryStore.java:663)

org.apache.hadoop.yarn.server.applicationhistoryservice.FileSystemApplicationHistoryStore.getApplication(FileSystemApplicationHistoryStore.java:156)
{code}
I debugged for a while. Only throwing NotFoundException will result in the
exception stack I've posted. While even throwing FobbidenException is still
okay. I still didn't figure out why it happened only to NotFoundException.
In addition, I found one more bug. getApplicationAttempts() and getContainers()
should return the empty map instead of null, which is the expected behavior
before, and callers assume not null too. Returning null will resulting NPE.
