[jira] [Commented] (SOLR-6969) When opening an HDFSTransactionLog

Mark Miller commented on SOLR-6969:
-----------------------------------

> This can happen after a hard crash and restart. The current workaround is to stop and wait it out and start again. We should retry and wait a given amount of time as we do when we detect safe mode though.
