             Summary: nodetool import expects directory
                 Key: CASSANDRA-19401
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-19401
             Project: Cassandra
          Issue Type: Bug
            Reporter: Norbert Schultz


According to the 
[documentation|https://cassandra.apache.org/doc/4.1/cassandra/operating/bulk_loading.html]
 the nodetool import should not rely on the folder structure of the imported 
sst files:

{quote}
Because the keyspace and table are specified on the command line for nodetool 
import, there is not the same requirement as with sstableloader, to have the 
SSTables in a specific directory path. When importing snapshots or incremental 
backups with nodetool import, the SSTables don’t need to be copied to another 
directory.
{quote}

However when importing old cassandra snapshots, we figured out, that sstables 
still need to be in a directory called like $KEYSPACE/$TABLENAME files, even 
when keyspace and table name are already present as parameters for the nodetool 
import call.

Call we used:

{code}
nodetool import --copy-data mykeyspace mytable /full_path_to/test1
{code}

Log:

{code}
INFO  [RMI TCP Connection(21)-127.0.0.1] 2024-02-15 10:41:06,565 
SSTableImporter.java:72 - Loading new SSTables for mykeyspace/mytable:

SSTableImporter.java:173 - No new SSTables were found for mykeyspace/mytable
{code}

However, when we move the sstables (.db-Files) to 
{{alternative/mykeyspace/mytable}}

and import with

{code}
nodetool import --copy-data mykeyspace mytable 
/fullpath/alternative/mykeyspace/mytable
{code}

the import works
