Thanks for all. Thanks for [~rkanter],[~djp]. I will try the HadoopArchiveLogs.
By the way I see that YARN-431 Stabilize YARN application log-handling. But
None of them basically solve the containers increase making too many small
files and causing a problem for the NN at once.
If we don't enable log aggregation and can provide "yarn logs" to get logs.
The problem will gone forever.
The thing I face is that we can't get the app and contianerReport relationship
when the app finish(Spark).
