Presto CSV Support

[sanjaytva]

I'm using presto version 0.257-df401fd.The hive metastore is on RDS Postgres. I tried to create a table on presto with the csv data on S3 using the following query

create table testing.csv_test (a varchar,b varchar)
WITH ( partitioned_by=ARRAY['b'],
    external_location = 's3a://s3-bucket/path/to/folder/',
    format = 'CSV')

The create table is successful but when tried to sync the partition

call system.sync_partition_metadata ('testing','csv_test','full')

We are getting an error
SQL Error [16777216]: Query failed (#20220708_071959_02186_pzp9i): org.apache.hadoop.hive.metastore.SerDeStorageSchemaReader class not found

After searching with few blogs as suggested edited the metasore-site.xml with the following property

metastore.storage.schema.reader.impl=org.apache.hadoop.hive.metastore.SerDeStorageSchemaReader

Still getting the same error. Any idea/suggestion on how to proceed further?
