Subject Full GC caused messages burst.
Date Wed, 18 Nov 2015 03:58:05 GMT

i would like to ask a question that is not really hadoop related.

i am working on a message system and find that every hour there happens 3 full gc, more or
less. and after each full gc, there is an message burst, and because there is an pipeline
to consume the messages, and it needs time to finish working on analyzing and even being persisted
on disk. always there encountered queue overflow, lot of messages are dropped even though
we have second cached queue in the pipeline.

since we have no way to completely avoiding full gc, can any one offer an approach to solve
these issues?

any comment is welcomed.
