export to parquet permission denied
I mounted an azure blob storage on my local linux, and I'm trying to export Vertica data into azure blob storage in parquet format, but I'm getting the error of permission denied.
Fusion=> export to parquet (directory='/mnt/xxxx/DIM_DATA/ITEM/xxxx') as select * from common.dim_product;
ERROR 5861: Error calling setup() in User Function ParquetExportFinalize at [src/ParquetExportFinalize.cpp:73], error code: 0, message: ERROR: Unable to make directory [/mnt/xxxx/DIM_DATA/ITEM/xxxxWvGZn4tW/] due to 'Error creating directory [/mnt/xxxx/DIM_DATA/ITEM/xxxxWvGZn4tW/] Permission denied'
Actually I give 777 to /mnt/xxxx folder, permission should not be an issue, I use Python pandas to export parquet file into the directory using the same linux user without any issue, I'm not sure what happened using Vertica export to parquet command.
