Description
Using TezUI sometimes times out...and the cause of it was that the query was quite large; and the leveldb handler seems like recreates the ObjectMapper for every read - this is unfortunate; since the ObjectMapper have to rescan the class annotations which may take some time.
Keeping the objectmapper reduces the ATS call time from 17 seconds to 3 seconds for me...which was enough to get my tez-ui working again
