Alejandro Abdelnur commented on YARN-649:
-----------------------------------------
[~vinodkv], for the new HTTP service returning logs, a 64K buffer is used to
stream the logs, so there things are bounded. For the existing web ui page that
display the logs, that is a different story, the current implementation is
loading the complete log in memory, creating the page, and returning it. The
later should be fix to do streaming similar to the new HTTP plain/text, but
that is another JIRA (just created YARN-911), here things are moving around a
bit in the web ui log service just to reuse certain logic. Are we good then
with the latest patch here?
