insert into column family with case sensitive column name - cassandra

Question

I am using the following Cassandra/CQL versions:
[cqlsh 4.0.1 | Cassandra 2.0.1 | CQL spec 3.1.1 | Thrift protocol 19.37.0]
I am trying to insert data into a pre-existing CF with case sensitive column names. I hit "unknown identifier" errors when trying to insert data.
Following is how the column family is described:
CREATE TABLE "Sample_List_CS" (
key text,
column1 text,
"fName" text,
"ipSubnet" text,
"ipSubnetMask" text,
value text,
PRIMARY KEY (key, column1)
) WITH COMPACT STORAGE AND
bloom_filter_fp_chance=0.010000 AND
caching='KEYS_ONLY' AND
comment='' AND
dclocal_read_repair_chance=0.000000 AND
gc_grace_seconds=0 AND
index_interval=128 AND
read_repair_chance=0.000000 AND
replicate_on_write='false' AND
populate_io_cache_on_flush='false' AND
default_time_to_live=0 AND
speculative_retry='NONE' AND
memtable_flush_period_in_ms=0 AND
compaction={'class': 'SizeTieredCompactionStrategy'} AND
compression={'sstable_compression': 'LZ4Compressor'};
CREATE INDEX ipSubnet ON "Sample_List_CS" ("ipSubnet");
The insert statements result in errors:
cqlsh:Sample_KS> INSERT INTO "Sample_List_CS" (key,column1,"fName") VALUES ('123','1','myValue');
Bad Request: Unknown identifier fName
cqlsh:Sample_KS> INSERT INTO "Sample_List_CS" (key,column1,"ipSubnet") VALUES ('123','1','255');
Bad Request: Unknown identifier ipSubnet
Any idea what I am doing wrong?

As I understand it when using WITH COMPACT STORAGE a table may only have one column other than the primary key.
As quoted in the manual:
Using the compact storage directive prevents you from adding more than
one column that is not part of the PRIMARY KEY.
For you that means you can only have one of these 4 columns in your table:
"fName"
"ipSubnet"
"ipSubnetMask"
value
(Alternatively, you could add 3 of them to the primary key definition.)
Thus it makes sense that the other three columns lead to an Unknown identifier error.
