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: https://github.com/apache/incubator-storm/blob/master/storm-core/src/jvm/backtype/storm/StormSubmitter.java?source=cc#L154
