Question

The following error message is displayed when the SST is generated in NebulaGraph Exchange:

org.rocksdb.RocksDBException: While open a file for appending: /path/sst/1-xxx.sst: No such file or directory

Answer 1

You need to check the following in NebulaGraph Exchange:

• Check if /path exists. If not, or if the path is set incorrectly, create or correct it.
• Check if Spark's current user on each machine has the operation permission on /path. If not, grant the permission.
