Sreenath Somarajapuram commented on TEZ-2159:
---------------------------------------------
Tried fixing the build, these are my observations:
- As we are batching, wouldn't the data be inconsistent / distributed across
time. Is that OK?
- Doesnt work in Ambari: When in Ambari view mode (probably because of the
proxy), data in processMultipleItems is coming as string and not an object. So
data.entities.length throws error. Might be better to parse if its a string,
and also check for the presence of data.entities array. Same with
processSingleItem.
- In 'that.send(cancelDownload);' , cancelDownload must be a string. And is it
intentional to put it in final, its getting called even when zip is ready to
save.
Suggestions:
- Wouldn't it be better to move most of the code in downloadDagJson to a helper.
- Later on: Separate dialog styles for each feature might make the UI look
unfinished, both column selection and download dialogs should be using the same
library.
> Tez UI: download timeline data for offline use.
