Description

Some log messages use erroneously "{}" in combination with a Throwable object. That's not placed in the log message by org.slf4j.Logger but added after the message:

CrawlDbMerge job failed {}
org.apache.hadoop.mapreduce.lib.input.InvalidInputException: Input path does not exist: file:...crawldb/current
