Review comment:
       During a log analysis with @pvary we realized that there's no info level 
log entry at the beginning of the worker process, which makes a bit more 
difficult to track down compactions which failed on the checks and did not 
reach the  
   `        LOG.info("Starting " + ci.type.toString() + " compaction for " + 
ci.getFullPartitionName() + ", id:" +
                   ci.id + " in " + compactionTxn + " with compute stats set to 
" + computeStats);
   `
   line. So we agreed to change this to info level.
