      Description

      The following assertion failure happens while importing data into RocksDB on 10.3.27:

      mysqld: /build/mariadb-10.3-Zg5BW3/mariadb-10.3-10.3.27/
      storage/rocksdb/rocksdb/db/compaction/compaction_picker_level.cc:136:

      Assertion `!level_file.second->being_compacted' failed.

      This could be because you hit a bug. It is also possible that this binary
      or one of the libraries it was linked against is corrupt, improperly built,
      or misconfigured. This error can also be caused by malfunctioning hardware.
       
      To report this bug, see https://mariadb.com/kb/en/reporting-bugs
       
      We will try our best to scrape up some info that will hopefully help
      diagnose the problem, but since we have already crashed, 
      something is definitely wrong and this may fail.
