Janarthanan commented on FALCON-1299:
-------------------------------------
Thanks for the welcome. Yes I could pitch in. Before that I don't have much
info on how this group works. If some one could guide with initial steps. Below
are few suggestions to be included in installation steps:
1. Tree structure for embedded and distributed mode separately.
2. Difference between embedded and distributed, though we can make it from the
names. But at first sight, I was not able to make any thing out of it.
3. How to build the falcon ? First I see a command "mvn clean install"
Again there is one more command with "mvn assembly...." . What's the need for
both, I am not able to make it, since i don't have much background on maven. I
just followed the instructions given there.
4. While opening the GUI, it prompts for user name, can there be a text to
either leave it as blank or default user name being displayed in the text box ?
Because it accepts any random text as user name. Now I am not able to give the
user name, even after stopping falcon and starting again, still it uses the
same user name. Not sure how it impacts the issue i posted.
5. When I built using the maven commands, I see two folders created inside the
/target folder as below, is there any difference or what's the purpose of both
the folders.
- falcon-sources-0.6.1
- falcon-0.6.1
6. Instruction to be given to add falcon directory to the PATH variable. Which
should be the working directory to run the falcon cli commands ? quite few
times, I got 'could not load main class' error. After couple of trails from
various folders, I got it right.
7. Details about the three tabs in GUI. But nothing to display in all the three
tabs at the first hit.
8. Should the endpoint for execution have https or http ?
What does rm stands for ? is it resource manager url ? What's the exact value
to be provided for execution endpoint. For the above issues i have posted on
time out, I can see that the error is because of not able to connect to below
url.
