bipinprasad opened a new pull request #3302:
URL: https://github.com/apache/storm/pull/3302
## What is the purpose of the change
Rebalance command completes successfully when --executor option has invalid
component name. This gives
the impression that command was successful. Change this behavior to throw an
exception. In addition, fix the help
text for --executor options to show correct format.
## How was the change tested
Run storm and rebalance using various correct and incorrect formats like:
bin/storm rebalance --help # to show corrected help text
bin/storm rebalance --executor spout:3 -w 1 word-count ## fail because of
spout:3
bin/storm rebalance --executor spout=3 -w 1 word-count ## verify correct
rebalance in Storm UI with spout=3
bin/storm rebalance -e spout=4 -w 1 word-count ## verify correct
rebalance in Storm UI with spout=4
