Table definition looks something like:
CREATE TABLE tbl1 (
field1 bigint,
field2 int,
field3 timestamp,
field4 map<int, float>,
field5 text static,
field6 text static,
field7 text static
PRIMARY KEY (field1, field2, field3)
) WITH CLUSTERING ORDER BY (field2 ASC, field3 ASC)
AND bloom_filter_fp_chance = 0.1
AND caching = '{"keys":"ALL", "rows_per_partition":"NONE"}'
AND comment = ''
AND compaction = {'class': 'org.apache.cassandra.db.compaction.LeveledCompactionStrategy'}
AND compression = {'sstable_compression': 'org.apache.cassandra.io.compress.LZ4Compressor'}

Following appears in debug log leading up to the error:
