Assume that you use Microsoft SQL Server 2014. When you drop a table that has a clustered columnstore index after the database is online and before the recovery is fully completed (specifically, the UNDO phase of the recovery is incomplete), you may encounter a recovery failure. Additionally, you receive the following error message:

<Date> <Time> spid#     Error: 3314, Severity: 21, State: 1.
<Date> <Time> spid#     During undoing of a logged operation in database '<DataBaseName>', an error occurred at log record ID (xx:xx:xx). Typically, the specific failure is logged previously as an error in the Windows Event Log service. Restore the database or file from a backup, or repair the database.
<Date> <Time> spid#     Error: 3414, Severity: 21, State: 2.
<Date> <Time> spid#     An error occurred during recovery, preventing the database '<DataBaseName>' (17:0) from restarting. Diagnose the recovery errors and fix them, or restore from a known good backup. If errors are not corrected or expected, contact Technical Support.
