Hyunsik Choi updated TAJO-589:
------------------------------
Component/s: worker
query master
Fix Version/s: 1.0-incubating
0.8-incubating
Summary: Add fine grained progress indicator for each task (was:
Show more informations of a task in web ui for profiling and monitoring)
I've changed the summary. This patch is more significant one than the previous
summary. This patch adds fine-grained progress indicator. It periodically
reports the progress of operators and in/out stats of tasks to QueryMaster.
