>             Project: Kafka
>          Issue Type: Bug
>    Affects Versions: 0.10.2.0, 0.10.2.1
>            Reporter: Jason Gustafson
>             Fix For: 0.11.0.0

> Our log recovery logic fails in 0.10.2 and prior releases if the topic name contains "index" or "timeindex." The issue is this snippet:
> {code}
> val logFile =
>           if (filename.endsWith(TimeIndexFileSuffix))
>             new File(file.getAbsolutePath.replace(TimeIndexFileSuffix, LogFileSuffix))
>           else
>             new File(file.getAbsolutePath.replace(IndexFileSuffix, LogFileSuffix))
>         if(!logFile.exists) {
>           warn("Found an orphaned index file, %s, with no corresponding log file.".format(file.getAbsolutePath))
>           file.delete()
>         }
> {code}
> The {{replace}} is a global replace, so the substituted filename is incorrect if the topic contains the index suffix.
> Note this is already fixed in trunk and 0.11.0.
