Subject [jira] [Created] (CASSANDRA-9207) COPY FROM command does not restore all records
Date Fri, 17 Apr 2015 04:49:58 GMT
Gaurav created CASSANDRA-9207:
---------------------------------

             Summary: COPY FROM command does not restore all records
                 Key: CASSANDRA-9207
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9207
             Project: Cassandra
          Issue Type: Bug
          Components: Core, Tools
         Environment: centOs, cassandra 2.1.1
            Reporter: Gaurav


Steps to reproduce:
1. run COPY TO command on keyspace A. (on my environment problem occurred on only 1 table
out of 19, only thing that io noticed is this table has >1500 records and other tables
has <1000 records)
2. pull the csv file and place it on machine (say machine B)where  other database resides.
(In my case this was another instance of amazon machine)
3. Now, run the COPY TO command on machine B. (both keyspaces, one on machine A and one on
machine B has same schema.)

Observation:
1. when COPY TO command is run for table having records > 1500. Command gave following
output:
Processing 1000 records
1573 records copied.

but when i tried to verify it by running below mentioned commands, i received only 273 records.
1. SELECT COUNT(*) FROM table-name;
2. SELECT * FROM table-name;


Note: please let me know if other information needs to be shared with you.

Also, is there any other way to take the back-up of keyspace and restoring it on other machine.
