Adam Lewis commented on STORM-241:
----------------------------------
I'm with you on keeping configs trim...Taylor originally suggested including a
config option for this when I filed the JIRA, I'm kind of ambivalent. As
Nathan said on the mailing list, the 15k default was a completely arbitrary
number...300k is another arbitrary number that works better for me :) I just
want the out-of-the-box experience to be smooth for people and this issue
was/is a thorn in my side in that regard. My only concern is that 300k was
specific to my particular network configuration (on that day of the week)...and
it is a number I arrived at by increasing 50k at a time until I saw diminishing
returns and speeds approaching SCP.
Perhaps the best way to handle this is incrementally. Hard code 300k now, and
if we start seeing requests to change the number _again_ then make it
configurable.
> "storm jar" underperforms compared to scp

> Key: STORM-241
> URL: https://issues.apache.org/jira/browse/STORM-241
> Project: Apache Storm (Incubating)
> Issue Type: Improvement
> Environment: Internet connected dev machine deploying to storm
> cluster on AWS. Storm 0.9.0.1
> Reporter: Adam Lewis
> Labels: configuration, newbie
>
> "storm jar" is very slow at sending the jar file, achieving roughly 10% of
> the throughput compared to SCP for the same network configuration. This is
> especially problematic when deploying jars from over the Internet.
> This appears to be related to the chunk size used to transmit the JAR file
> over the thrift protocol. Anecdotally, a 300KB chunk size (compared to the
> currently used default of 15KB), achieved performance in line with scp.
> Default can be overridden in the BufferFileInputStream ctor:
