László Bodor updated HIVE-27511:
--------------------------------
Description:
When investigating TezAM OOM issues, a common problem is a huge conf. In this
we usually do the following:
1. ask for heapdump
2. analyze heapdump, and find big UserPayload
3. looks for configuration properties in payload to blame
4. figure out how to reduce the payload
I think with a handy confuguration insight log message in HS2, we need to do
only 4) (as 1) 2) 3) can be complicated)
> Print Tez processor payload insights
