Josh Elser updated ACCUMULO-3274:
---------------------------------
Labels: newbie performance (was: newbie)
> MinorCompactor repeatedly toString()'s outputFile
> -------------------------------------------------
>
> Key: ACCUMULO-3274
> URL: https://issues.apache.org/jira/browse/ACCUMULO-3274
> Project: Accumulo
> Issue Type: Improvement
> Components: tserver
> Affects Versions: 1.6.1
> Reporter: Josh Elser
> Labels: newbie, performance
> Fix For: 1.8.0, 1.7.1
>
>
> Noticed that {{MinorCompactor#call()}} repeatedly calls {{getOutputFile()}}
> which ultimately calls {{Path#toString()}} each time. This isn't very
> efficient since we're repeatedly calculating the same thing and creating a
> bunch of short-lived objects.
> The output file name isn't going to change mid-MinC so the MinorCompactor
> should keep a local referenced to the result from a single call to
> {{getOutputFile()}} and use that local variable each time.
