László Bodor updated TEZ-4333:
------------------------------
Description:
Currently, tez.generate.debug.artifacts saves a serialized protobuf file, which
is hard to read because it just encodes the user payload. At the same time, tez
AM logs a readable json file into the tez AM logs but only at DEBUG level. I'm
proposing that tez.generate.debug.artifacts could write this readable json into
a separated dag json file, this way:
1. we can use tez.generate.debug.artifacts to produce one more useful file
2. don't have to set AM log level to DEBUG if we're only interested in the dag
plan
