maxwellguo commented on CASSANDRA-15301:
----------------------------------------
you are right ;
export means export sstable file to other place.
during this export , a new table is created and data is put , but when you use
the export data to do restore , then the new created table 's data is lost, at
least can not
be read;
also I have fix this problem.
I want to know if this is a problem and the patch can be submit.
