# Will test following scenarios:
# 1. Hit crash point on completing drop of all indexes before creation of index
#    is commenced.
# 2. Hit crash point after data is updated to system-table and in-memory dict.
# 3. Post truncate recovery, abruptly shutdown the server.
#    On restart ensure table state is maintained.
