             Summary: Log recovery can fail if topic names contain one of the index suffixes
                 Key: KAFKA-5382
                 URL: https://issues.apache.org/jira/browse/KAFKA-5382
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.10.2.1, 0.10.2.0
            Reporter: Jason Gustafson


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.
